Working on a 69 Roadrunner. Broadcast sheet indicates no radio but one was installed after manufacture. I have reason to believe that the right fender was replaced at one time and has what appears to be a correctly manufactured antenna hole. I want to make the car as original as possible so no antenna. Does anyone know if all fenders were manufactured with a hole, and a plug was used to fill it for no radio cars? Or was a fender with no hole used?
