I owned 2 challengers years ago 71 hard top n 71 convertable, restored both n enjoyed them. Sold both n now 2 wifes n 4 children later i located n bought a 70 challenger that was sitting indoors fo 26 years. i'm going to keep n restor it. The question is, the car comes with a power sun roof that works perfect, and it looks very factory instaled. Did the challenger ever come with a power sun roof? was it a factory option? does anyone know?
