Leave it to me to fan the flames. If the car was an rs/ss, it will only be identified by ss badge. The hideaway headlights rs option is identified by noticeing the car has hidw away headlights.
Amazingly, there are still lots of folks who don't realise that there was an rs/ss option. The only thing I know about Camaros is that the crayon scribble that everyone loves to put on their firewall wasn't on it when the car was made.
The point is that if rs and ss fenders are different, the fenders could be rs fenders but are identified as ss because that's what it said on the car. It's the same thing as the kid who just hollered out nice firebird. When his buddy asked him how did he know it was a firebird, the kid said "Says so on the fender." The only mistery is whose story is it?
I just so happen to have a picture of a 7 rr/ss vert, that was sitting in front of my parentss' house on 8/22/81, 31 years ago yesterday. It's kinda' sorta' a picture of an rs/ss. You gotta work with me on this one. The car is sitting just behind mine.
And in the picture of my present car, taken sometime between 85 and 87, where the hell did those doors and decklid come from?
