I had a 67 butternut yellow rs camaro. I am doing research on the value of it. But I need some things clarified on it. I was told that sense it had hide away headlights that it was a rs/ss. It was a convertable and had the 302 engine which was the z28 motor. But the only emblems it had were the r/s on the back and front and the engine on the front fender. Was this engine really rare in a rs/ss? How many were made? And any good sights to find more info? Also is there any way to find the vin # of old cars you used to own through dept.of motor vehicles, credit history, title search sights ect.?
