I apologize as this has probably been asked before, but I am looking at a 70, seller who seems very straightforward said the frame was rusted badly on the car. He found a 70 GTO frame that was in excellent condition, already sandblasted and boxed. Guy was building a race car and gave up on the project. So the seller put it under the 70. That should not be an issue? He put 3 coats of satin black epoxy primer a d all new body bushings before setting the body on. Thanks all
