74 sport to demon???

all parts from the 1970-1976 duster the 1971-1972 demon and the 1973-1976 dart sport interchange with each other your going to need 1970-1972 doors as well since the inner skins are diffrent and make sure that the 74 sport is not a space saver with fold down back seat since the demon never had one, also the rear quarters need to be fixed to if your making it into a 1971 to accept flush side markers unless your turning it into a 1972 then you can leave the side markers alone
