I am looking at an 1969 Camaro RS/SS. It’s not totally original by any means. As far as the hide away headlight components. What are some signs I can look for to determine if this car is possibly an original RS. The current owner stated the door don’t operate unless it’s done manually. The rear valance does have the back up lights but haven’t confirmed it to be original. The car has had the quarters replaced.. it is a LOS car.

Thanks,
Ray
