I'm currently in the process of restoring an old 1968 MPC Formula S glue bomb. I'm cannibalizing parts from the repopped MPC/AMT 69 'cuda kit. Once upon a time I was the proud owner of a for real 68 383 4-gear fastback.. I'm hoping to replicate it.
Both these kits are have promo like belly pans with suspention and exhaust molded in. I toyed with the idea of using a Mr Norm's 68 Dart as a donner chassis but decieded that it would be a lot of work for a car that would seldem have its underside checked out.
At one time Perry"s Resins had a conversion kit to back date the 69 kit to a 68, but I don't think he does mail order any more.
Thanks
