Hey guys noob here with a probably noob question. I have a low mileage 95 9C1 Caprice that I want to transplant the majority of into an 84 Cutlass Supreme Brougham. The engine transmission radiator fans and ecm are easy enough. My question lies in getting the disc brake 10 bolt posi rear under this body. I know about some custom upper control arms that are available what else would be required and what is the width difference? Is this a viable swap and worth the effort? Could I use the 5 on 5 front rotors on the stock spindles? Thanks in advance.
