Re: Drivers side sag? (Ed T)
Welcome to the club! :lol: I just got back from cruise nite & there was a really nice 73 conv that has the same problem. Just like my 71. :lol:
I wonder why I never notice that condition on the C2 cars? :confused:

My '71 too has a slight list to port.
Like I told the dumbazz that pointed it out to me
"It was designed that way to corner better" :yesnod:

My 73 does the same... about a 3/4" sag in drivers rear (a comment like this should stir some comments :lol: )
I replaced the rear spring and no difference.
Oh such is life. :cheers:

Re: Drivers side sag? (VetteNut72)
It was a real PITA to replace the #4 mounts. The frame bracket, bushing and bolt had all fused together into one mass and the Mount itself which attaches to the fiberglass, was almost completely rotted away. I placed wet towels everywhere and a friend brought over his "blue wrench" and we cut out all the bad stuff. I was able to save the frame mounts. Bubba had previously worked on this car many times in its past life and he did a good one on the right side inside mount. He fiberglassed it in! When I replaced everything (had to chip out all the fiberglass) I used screws and loktite to hold the inner and outer mounts together instead of poprivits which are stronger and easily removed without drilling. I used poly mounts to replace the solid metal bushings that were there originally.
PITA factor : up there with my trailing arm replacement but thats another story.

You can check the archives, this has been posted before. My 69 was the same way. The distance from the frame to the ground was very close to being equal measuring from the same points on each side, but not the body. Up to and including 72, they used aluminum pucks between the frame and body plus steel shims. In 73 they went to a rubber isolator puck to reduce a great deal of vibration from the chassis to the body. I upgraded to them when I did my body off restoration.
The simple consensus seems to be that most C3's lean with the passenger side being higher. The bodies must have been jigged wrong. Mine was out by nearly 3/4's of an inch at the back and about 5/8's inch in front.
You can crack the body if not done properly, but an equal number of shims needs to be either added or subtracted from one side or the other to make it sit level. DON'T JUST ADD SHIMS TO THE BACK CORNER MAKING IT APPEAR LEVEL AT THE REAR! YOU WILL TWIST THE BODY AND CRACK SOMETHING EITHER SOON OR DOWN THE ROAD* (pun intended) ;)
The car is bolted to the chassis at 4 points on each side, plus the bumpers.
