I see 55-57 Chevys, 68-72 Chevells, 2000-2010 Monte Carlos, Grand Prix, a 1966 Corvair all running in the SS class at many tracks and I think it's cool but they all are built on a metric GM chassis which is not the factory chassis for those cars. I want to put a 70-81 Camaro body on my metric chassis but cant get an honest answer whether this is legal or not. If the cars I just mentioned are so should what I want to do. anyone care to comment?
