I'll try to make this short. Friend bought a dart and decided that it was too rusty for him to save. Frame rails are gone mostly fenders are chewed up trunk is paper thin, floors paper thin. He scored it cheap but it ran and drove. Anyway he pitched me the idea of buying a good body and just switching the vin tags and drivetrain so it was legal to drive. I told him it probably wasn't legal. But I've heard of people selling titles and the dash vin and fender tag together at swap meets. So what part of this makes it illegal. Is there a loophole I need to be aware of? What can he do to make it legal?
