Wouldn't mind owning that Formula myself.
The 70-72 flat core support is now repoped. Like Steve said the 70-72 fenders are unique due to their inner structure, but any 70-81 fender can be made to work. The door skins are all the same,but the inner structure changed in 75 and this needs to be modified to use the early door panels and like the Camaro the Door handle length changed.
Steve's car is pretty nice isn't it....These errly Birds are really attention getters
