The body of a 1976 corvette is held on by eight bolts that attach to the frame. there are tow bolts near each rear tire, one in front and one behind. There is a bolt in front of the doors on each side and then two on the firewall. There are also bolts that attach the bumper covers to the bumper which will need to be removed. Also, the front bumper brackets will need to be removed as the pass through the inner fiberglass fender. Other than misc grounds to the body and removal of wiring harnesses, you should be able to remove the body.
