No problems with clones, I can't go to chrysler and order a 1970 cuda off of the production line today and go throught the book options and as many of these cars that are soon to be one with the earth, (like the multitudes you see on Cars in barns) are being destroyed I think you should make what you want and enjoy it, don't sell it off trying to fake someone into thinking it is all origional.
Mine will stay GranCoupe interior / exterior but is all cuda in drivetrain most of the parts are era correct or off of other cudas or challengers, some are year one repops, none makes it any less of a mopar. Wouldn't it be great if you could go to Chrysler and order a 1970 Gran Coupe with the 440 or E'MI Option.
