all these things

I thought, again, that maybe I should revive this stupid blog, and I found that I'd already written most of an entry and left it as a draft.  I didn't publish it, because I had a list of other stuff I thought I should talk about and I was only halfway through the list.  Well, looking at the list now, most of what was left looks boring, or unimportant, or I've forgotten the details now.  All of which fits the theme of this blog pretty well, but I think I'm just going to punt on all of those things, except for one, which will possibly go into a future entry.

Anyway, my last entry was a first effort at getting caught up on all the stuff that happened after I got the car home from the body shop for the second/final time.  I got maybe halfway through all that stuff, and then just decided to punt and publish, so now I need to get through the other half.  As the character Jeff Jordan says to the character Pete Aron in my favorite racing movie (Grand Prix), "Go another halfway!!!"

I talked in a previous post about how I had problems with the clutch pedal stop latching onto a bolt on the firewall when the clutch pedal was depressed, which made the car very awkward to drive.  I tried to fix that by modifying the clutch pedal stop, but I still had issues with the clutch.  Sometimes it just felt kind of "creaky," like there was some excess friction in the master cylinder.  It didn't seem right, and I eventually happened to hear about a clutch arrangement from another company that I thought might work better.  I had originally gotten a master cylinder from McLeod, because that was the company that I got all my other clutch stuff from.  But, they didn't have a master cylinder that was meant for my car, so I'd tried to make something else work.  Eventually I heard about a "universal" master cylinder from American Powertrain, and I saw some video of how it worked, and I thought it looked like it would be an improvement.

I think the big problem with the other master cylinder I tried to use was that when it was bolted to the firewall, it was not parallel with the pushrod that connected it to the clutch pedal.  I got it pretty close, but apparently "pretty close" was not close enough.  This resulted in side-forces on the master cylinder piston, which resulted in the "creaky" operation.

With the American Powertrain universal master cylinder, it uses a mounting bracket that is hinged so that the angle can be adjusted in order to make it parallel to the pushrod.  The photo below shows the American Powertrain master cylinder mounted in the Impala, and you can see the hinged mounting bracket.  After the position has been adjusted, the bracket is locked down so that it won't move out of the correct position.

So that sorted out the clutch pretty well.

Another thing that needed finishing was installing the oxygen sensors.  I talked in an earlier entry about the work I did to install the display in the dashboard, but now that everything was together and the exhaust pipes were under the car, I still needed to install the actual sensors, and finish the wiring between the sensors and the display.

There's three wires for each oxygen sensor, plus a ground for each, so with two oxygen sensors that makes eight wires to run through the firewall.  I didn't want to just put another hole in the wall and run wires through it, so I got a twelve-pin bulkhead connector from McMaster-Carr.  The photo below shows the connector, on the engine side of the firewall.

One nice thing about this connector is that the terminals install from the back side of the plugs, which makes it relatively easy to install new wires if you want to add more later.  If something else needs to be wired through the firewall, just unscrew the nut that clamps the gland down on the wires, crimp a terminal on the new wire, stick it through and push it in until it clicks, then clamp the gland back down on all the wires.

Once the oxygen sensors were working, I had some feedback on the air-fuel ratio.  It showed that the engine was running pretty rich, which was no surprise.  Carburetors usually come out of the box running pretty rich, because it's better to be on the rich side than the lean side, and they don't know all the particulars of your engine, or where you plan to run it, etc., etc.  I decided to lean it out by going two sizes smaller on the primary jets, for starters.  That seemed to show some small improvement, but it still appeared to be pretty rich.  As it turned out, though, for those couple of months in the Texas "winter," when the temperature might be in the 40s in the morning and the air is dense, it runs about where I would want it to be all the time.  I wouldn't want to go much leaner than that, so I guess by letting it run a little rich for most of the year, it ensures that I won't be too lean in the winter months.

After I had been driving the car a little while, I stopped to get gas one day, and when I twisted the gas cap to remove it, it kind of popped off into my hand as soon as it was unlatched, and there was a "PUFF" of gas vapor in my face.  Well that's odd....  I had gone to some trouble to keep the factory gas tank vent line in place, because I didn't want to disturb its grommet where it passes through the floor of the trunk.  The vent line connects to the front of the gas tank, at the top, and then runs through a hole, up into the trunk, then loops back down, passes out through the same hole, and has an open end to vent to atmosphere.  The purpose of running up into the trunk is just to get the high point of the vent line high enough so that gas won't slosh out of it.  Because the line passes through the same hole twice, it takes a special grommet with two holes in it.  I didn't know where I could get a replacement grommet, and I was afraid that it was probably so old and dried out that it would crumble if I tried to remove the old line and put a new line through it.  Well, one thing I never thought to do at the time was to verify whether or not the vent line was open.  Sure enough, it seemed to be plugged solid.

I was able to get a stainless steel reproduction vent line, and even had a few different options for where to get it.  I think I tried Year One first, because they seem to have the best stuff, in terms of matching the original parts and fitting up correctly.  But, they wanted to charge me something ridiculous for shipping.  The part was something like $40, and I hate to even say this because it sounds too ridiculous to be true, but I think they were going to charge something like $100 for shipping, just because the line is an "oversize" shape.  It only weighs a couple pounds, but they had this huge additional shipping charge because of its size and shape.  Anyway, I ended up looking around, and eventually found that Classic Industries had the line for $35, and I was able to order it when they had a deal going for free shipping.  Free, by my math, is a better deal than $100.

The photo below shows how the line loops up and over in the trunk.  It seemed to be a little longer than the original, and its highest point was right up by the body work.  It was actually right against the steel.  I was worried it would vibrate and cause a rattle when driving, so I decided to get a P-clip with a rubber sleeve on it, and I drilled a hole to bolt that clip to the body work, thereby stopping the line from rattling.

The next photo below is taken from inside the car, looking towards the back window.  A couple inches under the corner of the back window, you can see the head of the bolt that I used to hold the P-clip.  It's relatively unobtrusive, and when I look out the back window while backing up, it sometimes catches my eye and makes me happy to know what it is.  If I ever get around to finishing the interior, I think it will be covered up by either the sail panel or the trim around the back window.

Once I was able to start driving the car, I noticed that it had a slight vibration at highway speed.  It was hard to say where it seemed to be coming from, but it seemed to be road-speed-dependent, so I thought it was probably something rotating, and something down-system of the transmission.  That pretty much left the driveshaft, the rear end assembly, and the wheels.

Out of all that, the wheels and the driveshaft seemed the most likely.  My first thought was that maybe the pinion angle had changed since I first set it.  Once the car is driven a few times, it is not uncommon for the suspension to settle, and maybe that had affected the pinion angle?  Coincidentally, around this time I happened to catch an episode of one of these custom-car-shop-reality-shows, and they showed a customer bringing his car back with a vibration after he'd had it for a month or two, and the fix ended up being correcting the pinion angle. Now I was onto something!

I re-checked the pinion angle, and it was off a bit.  I had used a free app from Tremec that lets you check the angle of the pinion, the angle of the transmission, and the angle of the driveshaft using your phone as an angle finder, and then it tells you whether you are within the allowable limits.  The first time I did it, it seemed like it was repeatable, or at least predictable enough that when I made an adjustment and re-checked, I could predictably move the pinion to the correct position.  But now when I went back to re-check it, it did not seem to be repeatable or predictable.  So this time I used a mechanical angle finder to take the measurements, calculated the result myself, and adjusted it until it was back in spec.  That made me feel better about the pinion angle, but it did not fix the vibration.

I had noticed by this point, also, that there were very slow oil drips from the seals at the end output of the transmission and the input of the differential.  I put together a theory that the vibration might be caused by the driveshaft being out of balance, and that the resulting wobble of the driveshaft was causing the seals to leak, as well.  I tried to research online a bit and see if anyone else had ever had a similar problem, but didn't come up with anything helpful.

I had ordered the driveshaft online from a place in New York (state), because I had read something about the importance of getting your driveshaft from a place that knows how to properly balance it, and because they bragged a lot on their website about how they balance their driveshafts better than anybody.  What they said seemed to make sense (they went into more detail than just saying they were better than anybody), and they asked for a whole page full of measurements when you place your order, which made me feel like they must know what they're doing.  So it was frustrating now to talk myself into thinking that the shaft wasn't balanced properly after all.  Still, if nothing else, they did send me a free t-shirt with the driveshaft (or maybe a free driveshaft with a very expensive t-shirt?), and it became one of my absolute favorite t-shirts, so that was certainly worth it.

By the time that I was second-guessing their work, however, I had now become aware of a driveshaft shop in town that has a very good reputation, so I decided to take my driveshaft to them and have it checked.  They're not open on weekends or evenings, so this required taking a day off from work.  When I went in there and explained what I wanted and why, one of the guys told me that he would recommend replacing the seals in the transmission and the differential and see if they still leak, because that would be cheaper than having them balance the driveshaft.  But, at that point I had already taken the day off and removed the driveshaft and driven it across town, and I just wanted to get it checked and get that over with.  So eventually they agreed to just check the blankety-blank driveshaft.

After running the check, one of the guys let me come back and see the test rig, and he showed me the results.  He said he could add one small weight and it might technically make it better, but based on what the rig was showing, he would not expect someone in the car to be able to feel any vibration from the very small imbalance that he had found.  By this time I figured I was wasting my time, but also I was already there, and we had come this far, so if we can make it a little better, let's do that.  So he added the small weight, and then I paid and took my driveshaft home.

(I was favorably impressed by their shop and their service, and later I bought a new driveshaft from them for my C10 when I repowered it with a big block.  I never did, however, get any t-shirt out of that deal.)

They were right, the driveshaft did not make any difference in the highway-speed vibration.  I kind of lived with it as it was, and it wasn't real bad.  After a while, if I recall correctly, it seemed like it was most noticeable when I had first gotten up to highway speed, and then it would smooth out a bit.  As I made it a point to pay more attention to it, and tried to figure out where it was coming from, eventually one day I decided that it felt like it was coming from the right front wheel.  I'm not sure how to describe how I thought I could tell that, it just felt that way.

To test the idea, I swapped the right side tires front-to-back, and sure enough, the next time I took it on the highway it felt like the vibration was at the right rear.  I pulled off just that wheel and took it to a local Firestone shop to have the balance checked.  They confirmed that it was out of balance, but said they'd probably need to apply balance weights both inboard and outboard in order to correct it, and was that OK?

What?

So, the tires were originally mounted at the shop that did the powdercoating on the rims.  I dropped off rims and tires, they powdercoated the rims and mounted the tires.  Powdercoating costs more than painting the rims, but it results in a more durable finish.  I wanted a durable finish because I didn't want my steel rims to start rusting immediately.  But a lot of people who get rims powdercoated are building show cars that they just want a high-quality finish that will look good.  A lot of those people will also choose, I learned, to have the wheels balanced only with inboard balance weights.  In that way, there are no weights visible on the outboard side of the wheel, which presents a cleaner look for show cars.  And, since many of these people will only drive their cars to and from shows, or possibly even just on and off of trailers, they don't really care if they sacrifice the quality of the balance job.

This was all news to me, but my assumption after the fact is that the powdercoat shop just assumed that I didn't want outboard balance weights, or maybe they don't even carry those type of weights.  Anyway, they never asked what I wanted, and they only used inboard balance weights.  So now I told the guys at the Firestone shop, heck yeah, balance weights everywhere, balance weights all around, whatever it takes.  So they added some outboard balance weights, and when I got the wheel back on the car, and up to highway speed ... smooth as glass.  Fantastic.

The next item is a relatively minor feature that most people will never even notice, but it's one of my absolute favorite things I did on the car.

I have struggled to find good joyriding roads in the San Antonio area.  Growing up in the Chicago suburbs, there were lots of nice forest preserves around, with roads that wind past ponds, through densely wooded areas.  They were relatively short runs, but it also didn't take long to get to them, and it was satisfying to just go out and drive around a little bit.  Texas, on the other hand, is a barren wasteland where nothing will grow.  San Antonio is, however, on the edge of what's reverentially known as "The Texas Hill Country." The Texas Hill Country has a lot of nice winding roads through hills, even if there are no ponds or forests to be found.  It takes a drive up the interstate just to get out away from the city first, though, so it's not really as convenient as being surrounded by forest preserves within the suburban area.  Oh, well.

Anyway ... one night I decided to go out for a joyride through The Texas Hill Country.  I just took I-10 up to 46, and then followed 46 back to 16, and took 16 back to 410, and then 410 home.  Out on 46 after dark, though, I had the headlights on, of course, and I was flipping the high beams on and off, depending on whether or not there was oncoming traffic in sight.  As I detailed in an earlier entry, I put in a row of toggle switches on the left side of the dash, and I put all of the headlight switch functions on those toggle switches.  Well now, driving around in the dark in The Texas Hill Country, I suddenly realized that I could not see any of those switches in the dark.  So there was a lot of fumbling around for the high beam switch every time I needed to cut them on or off.

I thought about it a little bit, and developed a vague idea for a way to light the switches, although I wasn't really feeling confident that I'd be able to make it a reality.  But I started lining up parts to try something.  I started by ordering a strip of LEDs off of Amazon.  The photo below shows the strip of 15 LEDs.  As I recall, the LEDs were wired in groups of three, so it was five groups of three, with the threes in series and the groups in parallel.  So, if you cut off one LED, only twelve would light, and the two on the end that you cut would no longer work.  It was a little longer than I needed, so I cut off the last group of three and made it a strip of 12 LEDs.  When I tested the LEDs, they seemed really bright, so I also got some resistors and wired them into the 12V wire to drop the voltage and dim the LEDs.  You can see the resistors in the photo below, too.

The next photo below shows a piece of aluminum angle.  I cut off a length of it, which is the bottom piece in the photo below.  I think each side of the angle was about an inch wide, and I cut one side of it down to half an inch.  Then I cut and bent one end to box off that end.

The next photo shows the same two pieces, but now they are flipped over.  You can see the top of the boxed end is shiny where I filed it smooth.

Next, I drilled a couple of mounting holes, and a hole for the wires for the LEDs to come through.  I put a rubber grommet in the hole that the wires would run through.  The part is shown with the mounting holes and the grommet in place in the next two photos.

The next thing was to paint it gloss black, to try to make it blend in with the rest of the dashboard.  The photos below shows it after paint.

The photo below shows a close-up of the boxed end, after paint.  I just cut the half-inch side short, and then bent the one-inch side down around it.  I think I had originally planned on a sharp angle there, but it ended up curving more than I intended it to, and I ended up liking the rounded look, so I left it that way.  I used some JB Weld just to fill any gap where sides met up, then I sanded and filed it smooth, and painted it black.  I am really happy with out it came out.

The next photo shows the underside, after the LEDs were in place.  The strip of LEDs had an adhesive backing, so you could just peel off some paper and stick it to whatever.  I wanted some added piece of mind that it would stay put, though, so I think I added some super glue along its length.

At that point, the light was pretty much ready to go, I just needed to mount it to the dash.  The photo below shows the row of switches I wanted to light, and you can see a strip of blue masking tape which I put in place to try to protect the paint when I drilled mounting holes for the LED arrangement.

The next photo shows another view, looking up to better show the mounting holes, and the hole for the wires.  I actually screwed up and scratched up the paint on the toggle switch panel when I drilled the hole for the wires, and I added that Pure Oil Company sticker to cover the scratches.

So now, the photo below shows the LED arrangement mounted in place.  If you don't know you're looking for it, you would never notice it.

But after I connected the wires to the power for the dashboard lights, when the dashboard lights are on there is now a nice amber glow to illuminate the toggle switches and their labels.  No more fumbling around in the dark.

I really couldn't be happier with how this came out.  Usually, I have a mental image of how I want a project to turn out, but I just can't bring all the details into reality.  I usually screw something up and end up with a compromised result.  In this case, it came out pretty much exactly how I imagined it, and it's one of my favorite things in the car now.

Anyway ... good enough for now ... more to come ... maybe ... sometime....

ketchup ... catsup ... ketchup ... catsup ... I'm in way over my head.

I want to turn this blog into something useful again.  At the end of my last entry, which I see was a very long time ago now, I think the body shop had done everything I wanted them to do, and it was time to bring the car back to my house and finish getting it ready for inspection so I could start driving it.  That started a crunch of doing "this and this and this," then realizing I also needed to do "this," which got me to the point of "one more thing," and "one more thing," and "one more thing."  I kept thinking I'd update the blog after I got the car inspected and driveable, but that finish line kept moving on me, and then at some point I lost track of where the line was, and it turned out the line was so blurry it wasn't a line anymore.  I finally got the car inspected and driveable, but there was still a list of things that I wanted to get done on it.  In fact, there is still (and probably always will be) a list of things I want to get done on it.

Anyway, the point is, there's some catching-up to do on this record of events, and I feel like I can't move on to other things until I get caught up on what's happened so far.  I made a list of stuff that's been done which I haven't written about yet ... my goal for this entry is to get through that list.

When I went to pick up the car from the body shop and bring it home, I had a taxi drop me off there on a Friday.  I paid my last bill and talked to the owner a little while, and then got in the car to drive it home.  When I started it up, there was a squeal that sounded kind of like a loose belt, but not really like a loose belt.  It hadn't sounded like that when I dropped it off, so it was a surprise.  I looked at the owner of the shop, and he didn't look surprised or concerned, so ... hmm.  I knew he'd driven the car to and from the shop that mounted the exhaust, so maybe it had been doing this the whole time he'd been driving it?  It had made the noise when I first started it up, but almost immediately got quieter once the car was idling.  I felt like I just wanted to get it home, and the taxi had already left, so ... I decided to just get going.  On the drive home, the squeal would get worse whenever I was accelerating at all, and it was less noticeable at steady speed.  Anyway, the car made it home without any significant issues.  Hooray.

So now ... what was this noise?  It didn't, upon further investigation, seem to be coming from any of the belts.  I tried running the engine and using a mechanic's stethoscope to find where the noise was coming from, but it was hard to pinpoint.  Eventually, I put the car up on ramps and rolled under it on the creeper while it was idling.  Using the stethoscope, I felt pretty sure the noise was coming from ... the starter motor?  How could that be?

It wasn't really a squeal, as I said earlier.  Sometimes it sounded like a squeal, sometimes it sounded like an intermittent mechanical interference, sort of like a "tink ... tink tink ... tink ... tink tink tink ... tink tink ... tink ...."  It was difficult to figure out.  Thinking that it sounded like it was coming from the starter motor, I ended up pulling the starter motor off for inspection.  Where the pinion slides out to engage the ring gear, there is a small bushing on the pinion shaft that stops the pinion at the end of its travel when it is engaged during cranking.  That pinion stop seemed pretty loose and had some questionable endplay, and I started to think that maybe it was interfering with the flywheel just enough that the flywheel was rattling the pinion stop on the pinion shaft, leading to the noise I was hearing.

To test that theory, I got some yellow marking compound from a local differential shop, the same stuff they use to check the pinion depth in a rear end.  I put some on the starter motor pinion, and also on the pinion stop.  I put the starter motor back on the engine, and ran it again.  Still had the noise, of course ... pulled the starter motor back off and checked it...

Aha!  Where I had applied the yellow marking compound around the whole circumference of the pinion stop, a stripe had been wiped off of about half its width.  This would seem to indicate an interference, and confirm my theory.  You can see the stripe of bare metal next to the yellow marking compound on the pinion stop in the photo above.  Also, the pinion stop should be constrained pretty close to the surface to its right, but you can see that there is a gap there.  This endplay seemed questionable.  So now my theory was that the pinion stop was sliding on the shaft and interfering with the flywheel.  If it were constrained to the right, it wouldn't interfere.

I got in touch with the manufacturer of the starter motor, and after some back-and-forth, I sent the starter motor back to them for inspection.  They did some rework to reduce the pinion stop endplay, and sent the starter back to me.  I put it back on the car, confident that the problem was fixed, and started it up.  Still making the same noise ... nuts.

So then what caused the marking compound to be worn off the pinion stop?  I don't know.  Maybe the pinion itself rides against that part of the pinion stop during normal operation?  In any case, it didn't seem to be the cause of the noise.

Back to the stethoscope.  Eventually, after a lot more hunting around, I finally had a breakthrough.  While revving the engine by hand and listening with the stethoscope, I finally realized that the noise wasn't coming from the starter motor, it was coming from an exhaust leak at the bottom of the header flange, directly above the starter motor.  A coworker had recommended some specific header gaskets to me, he said they worked real well in his experience, and he said they were reusable.  I like things that are reusable, and I like things that work really well, so it sounded good to me.

Well, as it turns out, even though they were supposed to be correct for my engine, the exhaust port holes in these gaskets were just ever so slightly larger than the sealing surfaces around the exhaust ports in my header flange.  In the photo below, the reusable gasket is laid on top of a more traditional disposable gasket.  If you look closely, you can see a sliver of the disposable gasket visible at the top and bottom of the hole in the reusable gasket, showing that the vertical dimension of the hole is just slightly larger on the reusable gasket.  You can also see a black mark at about the five o'clock position on the hole in the reusable gasket.  That is where the exhaust was leaking out past the gasket.

The reusable gasket is made up of layers of soft aluminum, and it is supposed to conform to the mating surfaces and create a seal.  With the leak moving past the surface of the gasket, the layers had started to delaminate, and they were vibrating against each other like reeds, creating the noise I had been hearing.

I pulled out the aluminum gaskets and replaced them with some more typical disposable header gaskets.  These still had some leaks, but at least the squealing "tink tink" noise was gone.  I drove the car like that for a while, just putting up with the audible leaks, and then eventually I made another attempt at a fix.  While looking for parts for another project, I saw some headers that said they didn't require gaskets, they said they had an extra thick flange that was machined very flat, and they said that if you just applied a high-temperature RTV silicone, that was all you needed for a gasket.  That surprised me, because I would have thought that even a high-temp RTV would just burn up and blow out when exposed to exhaust gases.  But they said it was supposed to work.  With that in mind, I ended up replacing the header gaskets on the Impala one more time, and this time I also applied a thin coat of high-temp RTV to the gaskets.  This seemed to work pretty well, and has held up OK so far.

Another thing that was clearly in need of attention, even before I got the car up to the body shop, was the throttle linkage.  It wasn't as noticeable, maybe, driving the car around my neighborhood, but on the way up to the body shop it became apparent that the linkage needed some improvement.  The stock linkage had mated up to the Holley throttle lever relatively easily, which makes sense, I suppose, as the top-of-the-line 396s in 1965 had Holley carburetors on them.  But I'm not sure if those Holleys in 1965 had the same throttle lever as what you get with the modern one-size-fits-all aftermarket arrangement.

Anyway, when I first connected the throttle linkage, I had carefully selected the hole on the throttle lever that I used by using the following criteria:  it was the only one that would move the throttle in the right direction (pull to open, rather than push) and had the right diameter to fit the post on the swivel rod end at the end of the throttle linkage.  There was another hole that would give a longer effective lever arm, but its diameter was significantly bigger than the post on the throttle linkage swivel rod end, so that wouldn't work.  But, as it turned out, using the hole that fit the swivel rod end post meant that the effective lever arm was on the short side.  That meant that the throttle linkage had less leverage against the throttle return spring, so it took a little more force than usual to press down the gas pedal.  That might have been OK, but the short lever arm also meant that a relatively small movement of the gas pedal resulted in a relatively large change in throttle position.  When you add that to the increased force required to press the gas pedal, it made the whole arrangement touchy and awkward.

So, after I had the car back in my garage, I disassembled the throttle linkage to rework it.  This essentially boiled down to creating a bushing to take up the difference in diameter between the hole in the carburetor throttle arm and the post on the swivel rod end.  I had some cylindrical spacers of different diameters and wall thicknesses on hand already, and I was able to cut off some short lengths and nest them together to make up the difference in diameters, then put some washers on the sides to help hold it all together once it was assembled.  Nothing real fancy, but an effective fix.  I'm not sure if I have any good pictures floating around at this point, but the two photos below show the first arrangement (top) and the new arrangement (bottom).

If you squint real hard and already know what you're looking at, you can kind of make out how the throttle linkage now connects to the throttle lever a little further away from the axis of the throttle shaft.

You can also see that there is a double spring arrangement for the throttle return springs now.  The one in the stock location didn't seem to reliably return the throttle to the fully-closed position, and I saw the two-spring arrangement available from Moroso.  It's made to mount to the Holley carburetor base, instead of running a spring to a point somewhere forward on the engine.  The bracket for the springs interfered with the dropped base of my air cleaner, but I was able to just bend the bracket down a bit, and it seemed to work pretty well after that.  I had to get one longer carburetor stud for that corner of the carb, in order to accommodate the thickness of the bracket.  The stud I ended up using was only available in a box of ten, so if you need anywhere between one and eight little-bit-longer carburetor studs ... let me know.  (I say eight, instead of nine, because I ended up using the same throttle return spring arrangement on the 396 that I swapped into my C10.  And I say eight, instead of eighteen, because I was actually able to find the box of nine spares when I needed one for the C10, so I didn't have to order a second box of ten.)

So, that sorted out the annoying exhaust leak noise and the annoying throttle feel.  The last thing I needed in order to pass inspection was functional windshield wipers.  It is possible to buy rebuilt/reproduction windshield wiper motors for the 1965 Impala, but they are astonishingly expensive.  I had a wiper motor that fit the car, which was in the trunk when I got it, but it was pretty beat up and didn't work when I tried putting voltage to it.  There were a lot of different Chevrolet wiper motors that all used the same electric motor, but mounted that motor on different mounting plates with different bolt hole patterns and different drive arm lengths.  I got an idea....

I bought a much cheaper windshield wiper motor that used the same electric motor, thinking I could transfer that electric motor to the wiper motor assembly I had for the '65 Impala.  Disassembly required drilling out a bunch of rivets, but once I had it apart I was able to clean everything up and apply a fresh coat of paint.  The rivets that held the original assembly together were not pop rivets, but I figured pop rivets would be OK for putting it back together.  The bare aluminum rivets even looked a little flashy against the fresh coat of black paint.  It was all coming together nicely.  I took lots of pictures, and I would quietly chuckle to myself as I worked on it, thinking about what a clever solution this was, and what a great blog entry it would make (at some indeterminate point in the very distant future).

Then I got it all back together, and it didn't work.  I don't even remember what the problem was, specifically, I just remember it didn't work, and I was disgusted and discouraged, and decided to cut bait.  I chucked all of that and bought an aftermarket wiper motor that was made to fit 1965 Impalas.  I think it is a late-model wiper motor for a Mitsubishi or a Jeep or something like that, and some company basically fits it with a mounting plate that will bolt up to a 1965 Impala firewall, and adds a drive arm that will work with the 1965 Impala wiper linkage geometry.  I think they use the same wiper motor with different mounting plates and drive arms to fit it to a wide variety of classic cars and trucks.  The downside is, it looks kind of like a late-model part, and doesn't really blend in with all the other underhood stuff.  The upside is, it has two speeds (the wiper motor I had for a '65 Impala only had one speed), and it's waaaaay cheaper than the rebuilt/reproduction 1965 Impala wiper motor.

One last complication was that the 1965 wiper motor has a constant positive voltage wired to it with a switched ground to turn it on and off, whereas the aftermarket motor is grounded and uses a switched positive to turn it on and off, so I had to rewire my wiper motor control to accommodate that change, but that was pretty straightforward.  At the time I just wired it for one speed, just to have something working so I could pass inspection.  I had that one speed wired to one of the toggle switches on my dashboard.  That was a minimal level of functionality, as the "park" function wasn't even wired up, so you would have to try to turn off the wipers when they were relatively close to their parked position at the base of the windshield.  That was a bit of a hassle, so later I swapped in a double-throw toggle switch and wired it so that flipping the switch up would put the wipers on low speed, and flipping it down would put them on high speed, and I used the normally-closed side of a relay to make it so that the "park" input is energized when the switch is in the off position.  (I should mention, the wiper motor came with a switch that would have made wiring much simpler, but I wanted to run everything through a toggle switch that would blend in with the other toggle switches.)

So, at that point I had everything I needed in order to pass inspection ... but the interior of the car still looked very bare, and I thought maybe it would help to ease the inspection process if it looked more like a finished car.  I already had carpet and door panels on hand, so I figured I might as well install all that stuff.

The photo below shows the car at the body shop, with no carpet and no door panels.

And the next photo shows carpet and door panels installed.  Also arm rests, window cranks, etc.

There's not really much to talk about there.  The carpet is molded to fit the floor, the door panels and other stuff are all reproductions of factory originals, so it all just kind of goes in place.  But you can see that it makes a big difference in making the car look more roadworthy.  There was a little bit of a hassle with installing the reproduction window cranks on the reproduction window regulators.  I had original window regulators for the door glass and rear quarter glass, but I'd gotten reproductions for the vent windows, because one of those was not functional and needed to be replaced.  The end of the shaft that the crank is supposed to pop onto didn't seem to have quite enough taper for the clip to pop over, so I had to do a little grinding on those, but it ended up all going together relatively easily after that.

That had the front half of the interior looking pretty sharp, but the rear half was still a little lacking.  With a stock interior, a lot of the back seat area would be covered by the back seat.  It would cover a lot of the floor, and also some of the lower half of the sides.  But since I left the back seat out, those areas were all uncovered metal.  I wanted to make some upholstered panels to cover the exposed metal on the sides of the car, at least.  In the photo below, you can see the exposed metal below the upholstery panel on the side of the back seat area.

I started by trimming a piece of cardboard to fit the areas that I wanted to cover.

The "hashmarks" represent the upper edge of the exposed area, but I left some extra margin beyond that point so that the panel would extend up behind the stock upholstery panel a little bit.

Next I got a couple pieces of corrugated plastic sheet from Home Depot and cut them to the same shape as the cardboard template.

I was actually doing this project around the time of the elections in 2018, and I was tempted to nab a couple of political campaign signs from some place, since those are also often printed on corrugated cardboard.  But I thought the chances were good that any candidate whose signs I used would eventually do something to disgrace him-/her-self, and then I'd know that their name was inside of my car somewhere, so I decided to just get some plain black corrugated plastic to work with.

Lastly, I covered each of those plastic panels with black vinyl from a fabric store, and attempted to affix it with glue.

I used a glue called E6000, which the internet assured me was really great.  It's not terrible, but I wouldn't say it is really great.  The vinyl started peeling away from the plastic relatively quickly around the edges.  But, it has mostly stayed in place well enough that I haven't bothered with trying to fix it yet.  You can see in the picture that there are visible lines where I put the glue on the plastic.  I guess maybe I should have smeared it out into a flat film of glue so that the line of the bead wouldn't be visible, but that's hindsight.  And it looks good enough for my purposes.

The last thing was to install the panels in the car.  I drilled some holes and used some small screws to attach them to the metal underneath.

It's not perfect, and if I were to do it over there are a few things I'd change, but it does the job well enough that I don't feel compelled to re-do it right now.  A large part of the floor that should have been covered by the back seat was still exposed at this point, but that will be a project for another time.

I can't find any pictures of the process, but I used a very similar method for making kickpanels to cover the sides of the inside of the car under the dashboard.  I was able to find reproduction carpet for that area, but the reproduction of the plastic panel that the carpet is supposed to mount to was backordered.  I kept waiting on the backordered panels, but it had been several months with no sign of them showing up, so I just made plastic panels out of corrugated plastic again.  The plastic panels are supposed to integrate plastic grilles to go over the fresh air vents down by the floor, so I didn't have those.  I found, though, that the metal grilles from the 1964 Impala would fit the same space, so I bought a couple reproductions and used those.

While I was installing my makeshift kickpanels, my phone rang ... I let it go to voicemail because I was squeezed down under the dash in an awkward position, and the odds seemed good that the call was just a telemarketer or something, anyway.  When I'd finished installing the panels, I listened to the message, and, in a classic case of the universe thinking that it's so goddam funny, it was a lady calling to tell me that the backordered kickpanels were finally available, and did I still want them?  I said sure, so now I have them in a box and someday I'll install them, but the makeshift panels are doing a fine enough job for now.

I'm not sure if I actually made all those interior panels first or if I did some or all of them after, but it was roughly around this time that I finally took the car to get its state inspection so I could register it for use on the street.  I hate taking vehicles in for inspections because I just don't like letting strangers drive my car, and I always wonder if they're going to nitpick something, so I wasn't looking forward to the inspection.  But, it needed to be done.  I ended up just taking the car to Jiffy Lube, because it was the closest place to my house where I could get an inspection, and I didn't want to drive any farther than I had to without license plates.  As it turned out, it was a lot of fun.  It was a big day for me, of course, and there were just three or four guys working at the time, and they were all very enthusiastic about the car.  They let me hang around in the garage while the guy did the inspection and they asked questions and told me about their cars and all that.  I've been back to that Jiffy Lube for inspections since then and been less satisfied, but I guess I got lucky on that particular day.

In many ways the state tech inspection process is kind of a farce, anyway.  To make the most of the situation, I tried pretending that this was a pre-race tech inspection.  If you're going to take five years of your life to build a pretend racecar, it is considerate, I guess, for the state to arrange a pretend tech inspection.

Anyway, the car passed and I was able to register it and get license plates and all that.  That brought up a new problem, though ... I'd gotten a new reproduction rear license plate holder, but there didn't seem to be anything available for the front license plate.  I'm still not sure how it's supposed to mount ... the front valance comes to a point in the middle, and there are a couple of flats where the license plate can be mounted, but it is obvious that the flat license plate can't be mounted directly to the pointed valance.  I checked all the reproduction companies, and I checked ebay for used parts, but I couldn't come up with a front license plate bracket.  I am still only assuming that such a thing exists, anyway, but I don't see any way for the plate to be mounted without something along those lines.  I ended up just ordering a couple of steel sleeves off of McMaster-Carr so that I could put the license plate bolts through the middle of the sleeves, and the sleeves would have enough length to hold the license plate out away from the valance.  I also ordered them with a pretty substantial wall thickness, so that they would hold things rigidly in place when everything was bolted together.  I put a couple little rubber washers between the steel sleeves and the valance, to protect the paint.  I don't know if the photos below are very clear, but I attempted to show how the license plate is held out away from the valance by the steel sleeves.

This puts the license plate somewhat inclined from vertical, but it does the job.

After I'd driven the car a little bit, I went to jack up the front end and discovered that my jack didn't fit under the front crossmember anymore.  My assumption was that the front suspension had settled a bit once the car had gone over some bumps and cycled the suspension several times.  Since then, I've also heard that supposedly new springs will sag a little bit after the first time they get hot from being close to the engine exhaust.  Personally, I think the explanation that things settle when the suspension is cycled makes more sense, but either way, the point is that the car now sat a little lower in the front.

There are lots of options for low-profile floor jacks, but I didn't really want to buy another jack if I didn't have to.  The cost is one thing, but also I just didn't want another jack taking up space in the garage.  As I showed in an earlier entry, my floor jack has a cradle that sits in the end that supports the car, and that cradle can be easily removed.  By removing that cradle, I was barely able to slide the jack under the crossmember.  This seemed to work fine, I could just jack the car up with the cradle removed.

Unfortunately, there's more to that story.  One day I had jacked the car up by that method, and then I finished what I was doing, and I was going to lower it back to the floor.  As the end of the jack goes up and down, it traces an arc.  The wheels on the bottom of the jack allow the base to roll so that the car can go straight up and down as the arm traces that arc.  Well, I was lowering the car to the floor, and--WHAM!!  It suddenly fell.  It turned out that the floor jack hadn't been rolling, instead the end of the arm had been sliding on the crossmember, and it eventually slipped off the back of the crossmember.  It put a dent in the bottom of the oil pan.  Fortunately, something stopped it from completely caving in the bottom of the oil pan.  Unfortunately, the something was the center drag link in the steering linkage, which was bent as a result.  This was a maddening development, but I ordered another center drag link (I had already heard/read previously that it is not a good idea to try to straighten one of these once it's been bent) and it was pretty straightforward to swap it in for a fix.  The good news was that the oil pan was not dented badly enough to interfere with the crankshaft, so that didn't have to be replaced.  The photo below shows the bent drag link (top) and the replacement drag link (bottom).

All in all, it ended up being a relatively easy fix for something that could have been much worse.  But the next question was, how to make sure it didn't happen again?  Well, there is a hole right in the middle of the bottom of the crossmember, and I thought that if I could make something that would engage that hole, that would keep the jack from slipping off the crossmember.  As I showed in that earlier entry that is linked above, I had previously made a transmission cradle that could fit in place of the jack cradle.  I had bought a steel rod that would fit in place of the jack cradle, in order to hold the transmission cradle in place.  I had some of that rod left, so I just cut a short length and tapered the end so that it would fit into the hole in the crossmember.

The next few photos show the piece that I made, and how that piece fits into the jack.

Because I love racecar stuff, I decided to add one more thing.  If you look at as many pictures of racecars as I do, you might notice that some cars have an arrow or a triangle pointing downward somewhere along the side of the car.  This is an indicator to help the jackman find the spot where the jack is supposed to be placed during pitstops.  I decided to do something similar, to help me find the hole in the bottom of the crossmember, and also just because I thought it would be a neat detail.  The next two photos show how I painted a white triangle and a white stripe on the black crossmember, to help me get the jack lined up with the right spot.

Yikes.  The car has some miles on it at this point, and I am kind of surprised, disappointed and embarrassed to see how beat up the front edge of the crossmember looks.  I know I have scraped a few speed bumps and other rough spots in the road here and there, but I guess I hadn't noticed that it looked this bad.  If you're thinking about lowering the front of your car ... this is what you may end up dealing with.  I used two-inch drop spindles in front, and I sometimes think maybe I should look at going back to a stock ride height, because (lack of) clearance can definitely be a nuisance.

All right, folks ... I am like halfway through the list of stuff that I wanted to get caught up on in this entry, but I think I'm just going to post this as it is for now, and try to get through the second half of the list soon.

As Hunter S. Thompson might have said, "Mahalo."

Time flies.  And sometimes that's good, and sometimes it's bad.  And sometimes it's false.  But it's always true.

Pretty much anyone who's reading this will already know that this blog is lagging severely behind the pace set by real life.  The project has finally turned a corner and entered a new phase which makes the blog seem almost irrelevant, so it's even harder now to get motivated to update this.  But I can occasionally be susceptible to a bit of completism, so here I am again.

At the end of my last entry, I had finally gotten the car to the point where I could drive it back to the body shop for them to finish up the work that I wanted them to do.  They had done all the rust repair and the black paint, but there were a couple things still left to do that required the car to be running and driveable.  I wanted a white stripe painted down the middle of the car, and I wanted them to hang the exhaust under the car.  But the painter and their exhaust guy wouldn't/couldn't take the car if it wasn't running, so after the body was on the car and the black paint was done, I took it back to my house to finish the wiring, give it a functional dashboard, put brake lights in it, wrap the steering wheel in electrical tape for no reason, and other details.  (I had planned to put links to relevant entries for each of the items in that list, but that short list is spread over more than a dozen relevant entries, so I decided to just link to the stupidest one.)

I kind of hate temporarily cobbling things together just to make them functional, knowing that I'm going to need to take it all apart and make it "right" later, so it took some time to get all those details finished the way I wanted them.  But, a technician at work once asked if it was almost done, and I said no, and he said, "Do you work on it?" and I said, "Almost every night," and he said, "That's good, if you work on it every night, it'll get done," and it turns out he was right.  Well ... of course, it can't be overstated that a project car is never "done," but he was right to the extent that I eventually finished enough work to be able to drive it back up to the body shop.

So anyway, the plan was to paint a stripe, hang an exhaust, install some hood pins, and polish off some other details.  When I dropped the car off for all this work, one of the guys at the body shop sold me on another idea, which was for them to create a sheet metal cover for the package tray area (the area between the back seat and the rear window).  He asked what I was planning to do to cover that area, and I told him I was just going to use a reproduction of the stock upholstery pad that would have come from the factory.  He suggested that they could cut out a piece of sheet metal and roll a couple beads in it to give it some rigidity and make it a little more interesting looking, and maybe that would look a little more like the "bare bones" interior of a race car.  I liked the sound of that, so I said OK.

This would be just one instance of what would probably become a trend of me driving the owner of the body shop nuts.  I had dropped the car off on a Friday, and early the next week I was thinking about the cover for the package tray area, and had an idea.  The first time they had the car, they had made a cover for the rear bulkhead, where the back of the rear seat would normally go, and it had holes in it for the roll bar supports to pass through.  I guess they must have put the bulkhead cover in place and then installed and welded up the roll bar, so it was all kind of interlocked and pretty much permanently in place when they were done.  I started thinking, if they turned the holes in the bulkhead cover into slots that ran up to its upper edge, and then bent the front of the package tray cover down to overlap the bulkhead cover, with corresponding slots so that the slots would overlap to form holes for the roll bar supports to pass through, then maybe the bulkhead and package tray covers could be disassembled and removed around the roll bar.  I drew up a picture to try to show what I was thinking and texted it to the owner of the body shop.

He almost immediately texted me back and said that the guy had just finished the package tray cover that morning, or the day before, or something like that.  I give it about a 50/50 shot whether that was actually true or he just didn't want to mess around with trying to make sense out of my drawing.  Looking at it all together after the fact, I don't think my idea would have worked very well, anyway, I don't think there was actually room to wiggle my package tray design into position around the roll bar supports and everything else.  But the cover they'd made looks pretty cool, and I like it, so that was one thing done.

One of the first things they got done after I dropped it off was to get it over to their exhaust guy.  I had written them some notes and drawn a picture showing what I wanted, just dual exhaust angling back to a side exit just in front of the rear wheels.  I didn't want any H-pipe or X-pipe crossover.  Conventional wisdom these days says that you've got to have an H-pipe or an X-pipe if you're serious about performance, but the testing I've seen shows that these are only worth about 5-10hp.  That is a very significant gain if you're trying to wring every available bit of power out of your engine, but I guess I'm not serious enough about that to prioritize it over other things.  I don't like the sound of an X-pipe exhaust, and I like the sound of no crossover better than I like the sound of an H-pipe.  Plus, the advantages of the X-pipe weren't discovered in NASCAR until maybe the 1990s, and I don't know if they were even using H-pipes yet in 1965, so I can always lean on the convenient crutch of "authenticity," which I carefully employ whenever it suits what I already wanted to do.  On top of those things, it just simplifies the exhaust arrangement and makes it easier to work on some things under the car if there's no crossover.

Anyway, then the other decision to make was whether to do a straight cut on the exhaust outlet, perpendicular to the length of the pipe, or whether to do a "bologna cut," where the cut would be parallel to the side of the car, and therefore at an angle to the length of the pipe, which creates a more interesting-looking oval-shaped exhaust outlet.  I like the look of a bologna cut, but in the end I decided it was too fancy for what was supposed to be race-car styling, so I opted for the straight cut.  The guy put in a couple bends that I wouldn't have thought to use, to help keep everything tucked up under the car better, and it came out looking pretty nice.

Another job on the to-do list was to install a set of hood pins.  Hood pins are a safety device commonly used on race cars, I guess as an added measure of security to keep the hood from flying open, particularly in a crash when bodywork is bent up and the latch mechanism may be knocked out of alignment.  They don't really offer much benefit on a street car, but I just wanted them for the look.  "Because race car," as the internet says.

There are a wide variety of different styles of hood pins available in the 21st century, but I just wanted the basic old 1960's style.  I discussed and clarified that with the guys at the body shop, but we did not talk about where specifically to locate the hood pins.  I thought it went without saying that they would go at the corners of the hood, similar to where they would be located on a 1970 Chevelle SS.  It just never occurred to me that anyone would put them anywhere else.  So I was surprised when I went to the body shop to pay my bill for the week, and I saw that they had installed them closer to the vehicle centerline.

I had been picturing this in my head, for years now, with the hood pins out at the corners.  Seeing it done with them in another position just looked ... weird.  And it was really bothering me.  I didn't say anything when I first saw them, because ... what can you say?  At this point, ten holes have been drilled in the hood (one for each hood pin to pass through and four for the screws that hold down each scuff plate).  Relocating the pins at this point would basically require buying a new reproduction hood, painting it black, and then re-doing the hood pin installation.  Not cheap, and I couldn't really blame the shop for not doing what I hadn't asked them to do in the first place.

I had first seen the hood pins installed on a Friday, and I kept thinking about them all weekend.  I kept looking at the photo I'd taken, and sometimes it would start to look normal to me, but for the most part it was still bothering me.  Eventually, I had the idea to check and see where the hood pins were located on the actual NASCAR 1965 Impalas.  There is a guy in California who has an actual NASCAR survivor 1965 Impala which he restored and has entered into some vintage racing events, and he has a website about the car and the restoration process.  I went and looked at the photos of his car, and I was surprised to discover ... his hood pins were in the same location as mine!  Well, this was with the exception that his car had a third hood pin on the centerline of the hood, but I never liked the look of that third pin and I had knowingly chosen to omit it from my car.  Anyway, somehow I'd never noticed that on his car before, despite looking through his website many, many times.  It still looked a little weird to me, but I felt a lot better about it, knowing that at least it was "authentic."  With time I got used to it, and now I think I actually prefer it.

So, that was the hood pins sorted.  Eagle-eyed viewers may have noticed some blue tape on the car in the previous photo.  This was supposed to illustrate where the stripe would/could go.  The owner of the body shop had laid out the tape and sent me a picture, trying to make sure we got the width how I wanted it.  You can see that the tape on top of the hood doesn't line up with the tape on the panel just in front of the hood.  We had talked about how wide it should be, and he laid it out at eight inches.  In another instance of me probably driving him nuts with my indecision, I told him that maybe nine inches would be better, so he moved the tape on the front panel out to nine inches so I could see how that would look.  I was kind of sensitive to the width of the stripe, because I had started building a scale model of the car at home, to see how the paint would look before I committed to something on the real car.  The first time I tried painting the stripe, I made it too wide, and it looked horrible, so it was really important to me that we get the stripe width correct.

Anyway, we ended up deciding on nine inches, until he sent me one more photo with it laid out at nine inches, right before it was going back to his painter.  I looked at the nine-inch layout, and that didn't really look right, either ... I texted him back and said ... I think it needs to be eight-and-a-half inches.  I couldn't hear him scream from all the way up in Schertz, but he did text me back and say, "OK, but this is the last time I'm changing it."  So it got painted at eight-and-a-half inches.  I like it, I think we got it right.

Over the course of the project, I had waffled a few times on whether or not I wanted the stripe.  Would it look good?  Would it look bad?  Would it draw too much attention?  If I was going to do it, should it be painted?  Should it be a vinyl decal?  The vinyl decal would offer the option of removing it, if I decided I didn't like it.  But in the end, I decided to go all out, to do the stripe, and to have it painted.  So the first time I saw it, I was really kind of nervous about whether or not I was going to like it.  And when I did finally see it ... I couldn't really say if it looked good, or if it looked bad.  More than anything, it just looked different.  I had gotten so used to looking at the car without the stripe over the past several years, the overwhelming first impression was just that it did not look familiar.

After a very short time, though, I got used to it, and I like it a lot.  I'm definitely glad that I decided to go for the stripe, because I think it really changes the look of the whole car, in a good way.  I think the styling of the '65 Impala makes it look very low and wide.  I think the stripe accentuates its "spine" and draws attention to the shape of its silhouette.  I think the stripe transforms the look of the car from something like a catfish dragging its belly along a riverbed, to something more like a cat with its back arched in warning.  I love the styling of the car, and I think it looks good either way, but the stripe sets this one apart.  Anyway, bottom line, I like the stripe, and I'm glad I made that choice.

I talked in earlier entries about how part of the reason I picked a '65 Impala for the project was because '65 was one of the last years before NASCAR started allowing bodywork modifications for tire clearance, so I figured I could get an "authentic," "correct" NASCAR look without having to cut up the wheel wells.  I also mentioned above that there is this guy out in California who has restored a real NASCAR survivor '65 Impala, and he was very friendly when I e-mailed some questions to him early in the project.  One thing I wanted to ask him was what size tires he has on the car.  They appear to be significantly larger than what came stock on '65 Impalas, and I think they are crucial to the look of the car.  In fact, sometimes I really don't even like the look of '65 Impalas that are restored to factory stock appearance, because I think their wheels and tires look way too small.  So, I was glad that the guy replied with some helpful information about the tires he has on the car.

However, back when I went to pick up the car after its first stay at the body shop, right before I arrived they had bolted on the front fender extensions that form the bottom of the front wheel well, and they discovered that the extensions rubbed the tires when the wheels were turned to certain positions.  So that was frustrating, since I thought I had already verified that these tires should fit.  At the time, they just removed the extensions and I took the car home to do my wiring, etc., and it was sort of left as an open item to be addressed later.  If you look at the first picture of the car in this entry up above, you can see that the front of the fender only goes down to a point just below the bottom of the headlights.  In the last picture above, you can see that now the fender extends down below the bumper.  That extension is bolted on, and it was just at its bottom corner that it would rub the front of the tire in certain positions.

I wasn't sure what to do about that, but eventually I figured maybe the body shop could just modify those extensions a little bit for clearance.  I started looking for pictures online to try to illustrate what I had in mind, and when I started comparing photos of stock Impalas to Impala race cars, I realized that it looked to me like the fender extensions had been modified on the original race cars!  That made me feel better about the decision to modify them, and it's such a subtle change, you would never notice it unless you knew what you were looking for.  So, that was another thing that got done during the second stay at the body shop, and it's one of my favorite things that they did for me.  The photo below shows that fender extension in place, after modification but before the bumper and the front valance were installed.

Watching the car come together, I was starting to develop some apprehension about the quality of the finished paint job.  Specifically, as I saw how nice it looked, I started to get nervous about messing it up.  I am still kind of fighting between wanting to be very careful not to mar the paint, and trying to force myself to just treat it like what it is, which, at the end of the day, is just a car.  At the time that it was at the body shop, I started to feel nervous about installing the grille and bumper and trim, etc., and worrying that I might scratch the paint.  Watching shows on the internet, you would see guys at high-end shops taping off edges, wrapping soft rags around corners, and using other tricks while applying the chrome items, to avoid damaging the paint.  I started thinking that maybe I should let the guys at the body shop do all that work, so that I wouldn't accidentally scratch or chip something.  To be honest, with hindsight, I don't know that they did any better job than I would have done, really.  There was, however, another factor involved in that decision, which was time.

All this work was happening through April and May, and at some point I realized that Memorial Day weekend at the end of May would be exactly five years since the first time I went to look at the car before buying it.  I thought if I could have them bolt up all those trim pieces, etc., I could get the car home on that Friday before Memorial Day, install some working windshield wipers, and get the car inspected and registered right at the five-year mark.  That made an appealing goal, but I could just see myself somehow dragging out the job of getting all that chrome trim, etc., installed over the course of another month, so I decided to let the body shop expedite things.  I went ahead and let them install the bumper, the grille, the headlight bezels, the front and rear emblems, the side mirror, etc., and of course they put that all together quite easily.

Along similar lines, part of the upside of letting the body shop handle all this stuff, in my mind, was that I figured they should be a lot more efficient and effective than I would be when it came to aligning panels, installing weatherstrip, aligning windows, etc.  There is room for adjustment built into the assembly process for fenders, doors, windows, etc., and getting all those things to line up right takes practice and know-how.  It wasn't something I was really interested in, relative to other parts of the project, so I figured I'd let them handle it.  In general, that went ... OK.  I'm not particularly picky about door gaps and panel alignment, especially compared to some people who are very fastidious about it.  Actually, the front door gap on the driver side looks pretty bad, but I kind of like how it gives the car some character.  I mainly just wanted things to be functional, although I guess I got mixed results on that front, too.

One particular problem was the driver side door fitment.  Aside from the issue with the front gap, the door also just wouldn't close and latch properly.  It never latched properly since I got the car, but even after some adjustment, it still wouldn't latch properly.  The guys at the body shop found that one of the three bolts that holds that door hinge in place and allows adjustment of the door alignment was broken, so they put some considerable time and effort into getting access to that bolt to repair it.  But even after that, the door still wouldn't latch correctly.  This went on for a few weeks, as other work was being done, or as things were paused waiting for parts, etc.  Every week I'd go up there and the owner would tell me what they'd tried for that door, and it still wouldn't latch.  Finally, somehow he decided that maybe the problem was in the latch mechanism itself.  He got a replacement, installed it, and it worked great.  Another problem solved.

On the other hand, out of the four side windows, I think only one of them ended up being adjusted to where it would keep water out.  I was able to adjust another one of them after I got the car back from the body shop, but even now I still need to mess with the door windows some more.  The owner of the shop told me he had done what he could with the windows, and he had asked his painter to try because he was supposed to be good at that, but they didn't get them quite right.  Sometimes it's a question of know-how ... sometimes it's a matter of nobody else is going to care about it as much as you do.  I've messed with them a little bit already.  I didn't get them right, either, but I think I know what to do next, when I get around to it.

One other issue was a large crack in the paint by the back window.  It ran down the seam between the top of the quarter panel and side of the fill panel that goes between the rear window and the trunk lid.  I had first noticed it shortly after getting it home from the body shop the first time, so I pointed it out when I got it back to the body shop for its second visit.  The owner took a look at it, and we talked about it, but as work progressed over the next few weeks, it was still there.  At some point, I asked about it again, and he said pretty much all the same things he'd said before.  All this time, I was thinking it was understood that the crack needed to be fixed, but another week or two later, maybe after the stripe had been painted, I mentioned to the owner that the crack was still there.  "Well, it's always going to be there," he said, which was when I first came to understand that he was thinking the best thing was to leave it alone.  Hmm.

Well, he is the paint guy, and the reason I brought the car to him was to handle all that stuff.  So, if he thinks the best thing is to leave it alone, maybe the best thing is to leave it alone?  Still, it kept bugging me.  We had actually arranged that I was going to pick up the car on a Saturday and try to hit my five-year target for inspection and registration, but finally on the Friday before, I called him up and said, "Man, I just hate that crack, what can we do to fix it."  Well, he didn't sound happy about that, but he said that if I wasn't happy with it then he'd fix it, at no additional cost.  So that shot the five-year timeline out the window, but I think it was the right thing to do.  And he did fix it up nicely, but it added some additional time to the stay at the body shop.  Anyway, that was just about the last thing to get done at the body shop before the car was ready to come back home to my garage.

So, while those guys were working on all that, what was I doing all this time?  Well, it was nice to have a little bit of a break from working on the car pretty much every night, but I did also still have some components that I could mess with.  The main item that I worked on during this time was refurbishing the fresh air vents that mount in the kick panel area down in the footwells.  These are vents which draw air from outside the car and can help to provide fresh air to the interior.  They are not connected to the blower system, so you don't really get any air flow if the car isn't moving.

The picture below shows how the vent assemblies looked when I got the car and started pulling things apart.

I wrote the "D" and "P" markings on there, to distinguish the driver and passenger side assemblies.  The outer housing is black plastic, and it looks like some kind of rodents were chewing on at least one of them.  The inner flap that opens or closes to control air flow is made of two thin pieces of steel, riveted together with a piece of rubber sandwiched between them.  The rubber extends past the edge of the steel, to seal the gap between the steel flap and the plastic housing.

I feel pretty sure that I took a lot more photos than what I have here, because I wanted to make sure that I got everything put back together correctly.  Unfortunately, the four photos included in this entry are all I can find now.  You can see that there are some pins and clips and things like that, mostly for connecting the cables that control the flap position, and holding the cables in place as they are routed from the control knobs to the vents.

The photo below shows one of the flaps disassembled after I drilled out the rivets and pulled it apart.  Around the middle of the top edge of the picture, you can see a bent piece of rod which forms one of the pins that engages a hole in the plastic housing, where the flap will pivot.  You can see a similar pin still connected to the steel flap at the far left edge of the photo, and that's where the cable that controls the flap position would connect.  The flap in the foreground has been disassembled, and what you're looking at is the rubber seal between the two pieces of steel.  The rubber is old and dry and cracking, and in some places completely broken off where it should be extending out to seal the gap.

After disassembling everything, I threw out the old rubber seals and took all the steel pieces to work to clean them up in a sand blasting cabinet.  After cleaning, I coated all the steel with a corrosion inhibitor, then spray painted them black.  I ordered a sheet of high-strength multipurpose neoprene from McMaster-Carr.  I picked the softest durometer rating they offered, thinking that would help it to conform to surfaces and seal the gaps.  When that arrived, I cut out a couple of oversized pieces, sandwiched them between the steel halves of the flaps, and pop riveted everything back together.  Then I took a ruler and marked a dotted line at a constant distance from the edge of the steel, then trimmed off the excess rubber along that dotted line.

I cleaned up the plastic housings as best as I could using mineral spirits, if I remember correctly.  One of the guys at the body shop had told me that something like that was good for cleaning up those old plastic parts without eating the plastic, and I think it was mineral spirits.  Anyway, after cleaning those as best as I could, I put everything back together, and I think they came out looking pretty nice.

All that having been said ... pretty much everything you see in that photo will be out of sight, down under the dash by the floor and hidden behind a grille, so you could easily argue that this was all a waste of time.  The only functional benefit was replacing the old rubber sealing surfaces.  But, it's satisfying just to take something apart and fix it up and make it nicer and get it back together and working again, so that was good.

One more thing that eventually happened with the fresh air vents:  after I had the car back home and was installing the vents, I found that I was missing one of the clips that hold the control cables in place.  The cables just have push-pull knobs under the dash, and each one runs through a spiral sheath.  So there are clips to hold the sheath in place so that when you push/pull the knob, all of the motion is transmitted through the cable to the vent door.  I had taken the cables to work and sandblasted them, too, to knock off some surface rust and clean them up a bit.  There is some other mounting hardware for the vents, as well, and I cleaned up some of that and replaced some of the rest of it with generic parts from the hardware section at Lowe's.  But, I was missing one of the clips for securing the end of the control cable at the vent assembly.  The clip is just a formed piece of metal with a hole in it, so I decided maybe I could just make a replacement.  I didn't take any step-by-step photos, but the pictures below show the end results.  The piece with nice sharp edges and a well-centered hole is the factory piece.  The one that looks like a piece of junk that someone fished out of a garbage disposal is the one that I made.  But, it's functional.

I think the basic process for making the part was to cut out a piece of sheet metal in the right size, drill a hole in it, then clamp it in a bench vise and put a bend in it, then hammer that bend over the shaft of a screwdriver to make the curve.  Then a hammer and a straight punch to make the little notch feature that grabs the cable sheath, and then I heated it up with a torch and quenched it in water to add some hardness so it would hold its shape.  I didn't get the hole in quite the right place, and I guess I miscalculated the required length, because the curve came up a little short of the original geometry.  I thought about starting over, to make a nicer one, but this one is perfectly functional, so ... it's fine.

So anyway, that's about it for now.  At that point, the body shop had finished everything I wanted them to do, and it was time to bring the car home again.  It still needed working windshield wipers before it would be ready to pass inspection, and there were still a lot of other details to address, but it was finally looking like something similar to a functional mode of transportation.

Coming up next time:  more stuff.
