I just came across this picture of 1973 Trans Am that has an ASC power sunroof, I don't believe I have ever heard of them as an option so I wonder if the dealer sent it to ASC like they did with my Monte to have one installed.
Maybe someone knew a guy who knew a guy... it's happened before.according to this list there was no option from the factory for a sunroof

the rear bumper guards were a factory option
