There is zero proof that is original sheet metal. The car has been 'restored/repainted' all bets are off.
There are many claims about how ‘original’ the car is yet the ducted hood was added, master cylinder, booster, rear springs, shocks, sound system and speakers are aftermarket replacements. The RS headlamp washer system, AIR system and clock are missing. Rear stripes are incorrect, steering wheel isn’t original. Trunk mat doesn’t belong; no 1st Gen Camaro had a spare tire cover. Has headers and a muffler shop exhaust system. Dash pad is badly warped, fuel tank is damaged, bell housing is not original.
In my 49 years of 1969 Camaros, I have yet to examine a real RS-Z/28 built with Camaro fender emblems. I have explained how it may have occurred. Last year an original paint Z/28-RS also built at Norwood a few weeks earlier was found in the AZ desert, rally-sport fender emblems intact.
