Sunroofs were offered and advertised for the "A" body cars. Brochures were offered to prospective buyers featuring the options that were available.
However, it is documented in Pontiac literature that the sunroof could be ordered for "F" body cars but wasn't "promoted" like was done for the large body cars.
"Historians" will argue the fact but when "money talks"........well you know.
The car on ebay doesn't appear to have the same cutout or as the typical ASC version offered at the time. Too bad there is no birdseye view of the roof.
