So I know that my 83' Monte has an inbuilt power sunroof from ASC that was dealer installed when new and I always heard that there was never an option for the Montes to get a power sunroof/moonroof but there is a guy on FM selling parts from his 87' Monte SS claiming it is factory installed but has no interior shots to send me, it looks more like the one I installed in my Regal. So is there anything verifying that this was not an option or maybe if you knew the right people.
