Restoration of burnish brown RS COPO

[bergy]

I removed the fenders and there was no marking inside of the fender extension. They look original, but no marking. This is an 05E car - maybe they didn't mark them all? I've attached a photo of the original firewall piercings showing RS hole. I would say that the car came with two rear speakers. I've had several '69 Camaros, but never anything but an AM radio with front speaker only. Does anyone know if an AM radio could be ordered with dual rea speakers, or would duals be for a stereo application? Also, the "30" on the heater box does tie out to the last 2 of the VIN. Could be coincidence, but somehow they had to flag the BB heater core on the X-11 code car. Regards, Bruce
