There are no nice reproductions available on these cars, there is one that Cbody Bob has we were going to use on his 1966 300 but when looking at it, it is only a flat sheet of metal and the grooves only slightly show on it. We decided to use good floor panels out of another car. The good part about that is all 1965 to 73 C-body pans can be used. We welded in 1968 Fury pans into his 1966 car and i used a 68 pan in my 1970 car.
