Default 69 C3 convertible restore

Weathers getting better and hoped to get back on my project. It looked OK when I bought it but went downhill quickly.



I have the birdcage repaired and back together. Still need to repair upper corners but things are moving in the right direction I'm sure to have many questions as this goes along.

Hi 69C3, I can sympathize with what you are going through. I thought I purchased a nice 69. Now 2.5 years into my restore I am starting to see the light at the end of the tunnel. Everything in your pictures look great. Nice work takes time and the details are important. Keep up the good work.

It's taken over both garage bays and part of the basement. I'm afraid to mention my wallet as well.

Thanks Rvzio I've been reading your post and Doorgunners post too. I have started putting the body and birdcage back together. Hope to post a few more pictures and ask a few questions later. Couldn't have made it this far without the Forum!!

Hi 69,
Cars can be pretty good at hiding problems they may have, especially from someone not quite sure just where to look, and also what the signs they may be seeing really indicate.
It looks like you'll have the 'opportunity' to get to know this 69 QUITE well before you're finished!
It's be interesting to follow along. You're starting about as near as one can be to the actual 'beginning' !!
Good Luck!
Regards,
Alan

Well your right C3, I forgot the money part, how could I. I wish I could forget the money part. Oh well, we each will have a nice car when we are done and have learned an awful lot about these chrome bumper cars.

Thanks for all the posts. I've dug up another picture, probably the closest to where car currently stands. Just mock up not all the rivets set.

I had a previous post regarding my decklid springs had been slotted at the mounting hole.

https://www.corvetteforum.com/forums...e-problem.html

I keep coming back to why? Definitely not factory so maybe the rear surround was replaced and bonded to low?



Measuring straight down to the underbody and up to the lower lip of rear surround I get about 10 1/8" . Any other convertible owners have similar measurement??

Default front clip

Hi C3 , I just noticed in the older picture that the front clip was missing the 1" cross bonding strip. Hopefully you have it. I have a pneumatic adhesive gun if you need it when you get to that point. It really saved from hand pumping.
Keep the pictures coming.

Good eye RVZIO. I have the strip somewhere in my pile of parts. Thankfully my son dropping his bike didn't cause more damage. It's a one piece HL unit, might try and find a good donor with factory glass.Pneumatic gun does sound like the way to go. I may take you up on that offer.

Rookie guess: the bolts were frozen on my hinge assemblies....maybe the previous owner managed to loosen the bolts 1 turn/then he used a dremel to notch them so he could wiggle the hinge assemblies out?

Mine measure 10 1/8" on my '68.

Doorgunner thanks for the measurement. I hadn't thought about frozen bolts but could be the case. Both sides are the same, new bolts tighten in the slotted area not up higher where the original holes are drilled. Everythings is an adventure with this car.

My Bubba used tall rubber bushings at the number four mounts. Most of the other aluminium mounts had corroded away and shims had rusted away. I'm starting from scratch..... and believe they sanded the door edges to make the gaps look right with the rubber mounts. I currently have 6 to 7 shims at number four mounts to get the gaps close. It's a new frame from vette products so hopefully that rules out any chassis problems. The adventure continues...

Hi 69,
Originally the 'shim count' was determined before the frame/chassis even met the body that was going to be dropped on it.
So the shims weren't used to adjust the door gaps. This of course was an 'ideal' situation since both front and rear clips were securely bonded/riveted to the birdcage structure.
How did you determine what shim count to begin with on your new frame?
Many people who no longer have an original shim count for their frame begin with 3 shims on each mount and then add/remove shims as needed. Is that about how you started with your 'unknown' frame?
Regards,
Alan

The fixture used to 'measure' the frame. (note it's still upside down)


The gauge used to determine how many shims were required at each body mount location. Note this picture shows the later rubber bushings rather than the earlier aluminum 'pucks'.

Hi Alan, great pictures! Not sure if it's right but I'm setting the frame to the datum in chassis manual. Then finding the highest body mount adding shims to the others until the difference, mount to mount is achieved as compared to the chassis page? I've been using front gage hole and #4 mount but may switch from #4 mount surface to bolt hole for trailing arms? First corvette so maybe I'm over-thing the process.

Hi 69,
I think the only thing I can add is to be sure to note that 2 of the of the dimensions are to the TOP side of the mount (2&3) and the #4 dimension is to the UNDER side of the mount. The symbol appears near the #1 mount dimension too, but it's unclear if that dimension it to the upper or lower side of #1???
Regards,
Alan

Default vette

I know when I went to do my shimming I had the doors on as well as the clip. I started with 3 shims at each location checking door gaps as well as overall body levelness. With the body on my pulley system I was able to lift the body enough to adjust the shims accordingly. The pictures shown are great but they are brand new cars and unfortunately the cars that most of us are restoring all have some kind of story. Its a big important step so be patient and get it to the best your car will allow it to be. Once that is accomplished the other things will start to show what needs to be done. Oh one more thing, don't be surprised if you have no shims at a location or maybe even 2.
You can do it!!! Oh I forgot that I had the correct tire pressure and on the ground. Worked for me, just trying to help, it's your car.
