Default progress on the 74

Pretty cool to see the stickers on the side of the door.



My son installing the seats. We will have to get the seats redone at some point. For now, he took the passenger side and installed it onto the driver side. Plus. we have to paint the rear back of the seats.


We got some other things done:
Reinstalled the fan. fan shroud and radiator hoses. Installed new bushing for the sway bar.
We replaced the seals on the headlight actuators. The headlights are still not functioning properly. I ordered a set of vacuum relays and new springs. My other son checked the vacuum at idle (~13 Hg).
All of the gauges work except for the speedometer. We have not tried to put it in gear yet. I have jacks but do not want to lift it until I am ready to do the brakes. My friend has a few sets of calipers. He said he thinks he has a set of stainless steel sleeve brake calipers. Ours are missing.
Changed the oil (wix, zinc additive and 5w30).
All of the lights are working.
Someone bypassed the heater so that will need to be addressed (new heater core and heater hoses)

We noticed a leak on the power steering rack. A few years ago the steering ram was replaced. Not sure if the lines are loose or what.
This weekend, I plan on getting him to lift the corvette up and go through the entire suspension plus check the gear and transmission oil. Discover any leaks we need to address. Also, I have a fuel filter that goes into the carb so we can replace it too.

Both door panels are loose. I have a rivnut set so I might just have him install a rivnut in the corner for now on each door The door panels are in rough shape but will work for now.

While you are flushing out the old brake fluid why not put new differential oil and transmission fluid/filter just to be safe.

Yeah, already have some redline gear oil in the garage. No filter since M21. Also, the brakes lines have no brake fluid in them since all have been replaced.

I think the rear end is leaking so I will fix that too.

just because heater is bypassed doesn't mean the core leaks. i fabbed a pressure tester with rubber hoses, t fitting, a gauge and a tubeless tire fitting. pressure test before pouring antifreeze onto the carpets. you also want to use shut-off valves to maintain the bypass when not heater season. these cars are warm enough without the heater running in july!

No fan either so might as well take it out and figure out what is wrong... Its not a big deal to pull out the heater core.

...that's only if you do not have A/C, otherwise it is more of a big deal.

Not when its all disconnected. The AC lines have no pressure at all. It was all disconnected by the previous owner. I am sure I will find the fan switch is in the same condition. Though, he did upgrade the AC system. It has a R143a conversion done to it just not charged or fully connected up.

I can see the leak on the passenger side carpet. Mainly, just need it for the defroster only.

Lights are working! The relay on the driver side needed to be replaced. Now, the lights go up and down on both sides.

Moving onto:
Check the fasteners on the suspension.
Check gear/transmission oil.
Check why the power steering is leaking.
Install radiator shroud seals
Install rear side marker and make sure the light is working.
Address any leaks

Interesting tibit. The LH rear marker was missing the red lens. 1974 the housing was made out of pot metal. I bought a replacement one stating it was for this year and come to find out the housing was made out of plastic. The stud mounts on the back were larger than the original pot metal. I cut off the housing on the plastic one and kept the lens intact then glued it onto the pot metal housing. I guess at some point later on the housing were no longer pot metal.

Its been slow working on the corvette.

Got the side marker installed.
The power steering is leaking really bad from the valve. We are going to upgrade to a borgeson unit.
Check the fasteners on the suspension.
Check gear/transmission oil.
Install radiator shroud seals
Address any leaks

My plan is to upgrade the brakes, steering and wheels.

I bought some bushings for the shifter levers. It needs to be adjusted. I have an alignment pin to set it right. Also, bought a new license light harness. Someone disconnected one of them. The front side headlight indicator switch was hanging down. I bought another one to mount up there. The other work is to fix the front passenger side fender. We will have to take it down the bare glass to see if we can get the passenger side to match the driver side. It dives down plus the front lip where the front nose connects is off on the passenger side. I might as well fix it while I can since I have all of the materials (hardener, resin and mat) to do the work.




He can drive it primered up for now. Same thing has to happen to the rear bumper. There is one crack but its all there to make fix it.

I got the heater blower to work. The switch was all gummed up. I cleaned it and now all four speeds are working properly. I figured out the horn is shot. I put 12V to it and nothing. Plus cleaned all of the ground connections and checked the ground to make sure it was grounded. I ordered a replacement horn.

Also ordered4 new brake calipers and power steering upgrade unit.

Horn works now. I replaced it with a non correct one. We will keep the old one if my son ever wants to restore it. A horn is required as part of the new safety DMV test. So that's good to go. Back to glass work. I had to make cuts on the front aftermarket fiberglass bumper cover to make it fit properly.

More glasswork:

I can work on it for a day then let it dry with a heat lamp then sand and add more glass the following day or a couple of days later. Slow work but its getting there.

Pressure tested the heater core. The heater hoses were sticking out of the engine bay. It held 15 PSI of pressure with water throughout the system. So not sure why it was not hooked up??? Oh well now, we can try to hook it up.

My 75 would get so hot in the footwells that I did ANYTHING to keep heat out of there. I disconnected/bypassed the heater core for that reason.

My son's 74 got some new shoes... 245/60/r15s Cooper Cobra Radial G/Ts. At first they thought about putting the white walls in... The manager said I think he would want the white letters out since its going on rallys. Why would you not put the white letters out? Exactly!

We also check the sending unit. Some of the rubber insulation was gone. I added some shrink tubing and a few zip ties to fix that problem. The float worked and the ohms were moving up and down when the float moved. Its a new sending unit. We cleaned up the connections and reinstalled the sending unit with new gaskets. I have not been able to check it to see if the fuel gauge is reading now. I know the gauge was working since we disconnected the power and saw it pegged to full.

We still have to address the speedometer not working. I am sure its the gear in the Muncie. I ordered a new plastic gear plus plan on testing the cable while its disconnected.

This weekend's task:
Replace rear gear oil
Check the fasteners on the suspension
Check the front bolts where jack installed the radiator
Lube shifter linkage with graphite spray
Buff and wax plus polish
Detail engine bay.
Check fuel gauge.
Check speedometer once the gear has been replaced and cable lubed.

Good to see you getting the next generation involved. My Father got me a 1966 Mustang when I was 14 or so. So it would be ready for me when I hit 16. I learned a lot about mechanical work and body work. Getting to spend time with him was a bonus. And you know what? I never wrecked that car, because I knew what it took to get it on the road in the first place and I sure didn't want to be on foot while all that happened because I was careless. Pretty smart of my parents. Besides, they always knew where I was...down in the garage.

We did the same thing with our older son. He is way of more of gear head than me and my younger son.
