I've got a 68 Charger that needs some roof structure and quarter panel structure. I've also got a 70 coronet parts car with clean structure. I know the roof skins are different for the 68-70 charger compared to all the other 68-70 b bodies but I'm assuming the roof structure is the same for all 68-70 b bodies. Am I wrong? Ideally I'd use the roof and quarter panel structure (not the skins) from the 70 coronet to repair the 68 Charger. Thanks in advance.
