1980 Cutlass Supreme 2 door

Have the body off and am replacing the body bushings. Im not sure who do buy them from. It is my understanding this frame is considered an A body?

 

Yours is a G body.

 

1980 is an A-Body designation... Actual G-Body did not start until 1982...,

 

1. Do you give two flips about staying original?
2. If the answer is no, then go to Summit, et al, and get a polyurethane cushion kit. Advantage is they'll stiffen up the connection between frame and body. Disadvantage- potential squeaks, but i haven't ever personally heard that happening. Also a slightly stiffer ride, but not overly so as to want to go back. It's actually a good upgrade. Get the kit and the new bolts if they don't come with the kit. Make sure to ask.
3. If the answer is yes, you'll need to find out all the various part numbers and seek out the long discontinued GM rubber pieces.

Good luck.
