Chris,
It is unlikely that the rear is original to the Camaro based on the data which exists (per Kurt). The COPO clues which you mention point in that direction, but are easily added to the Camaro.

Since you appearantly have a low miles original sheet metal and unrestored Camaro, I would say that it would behoove you to pay for an expert opinion as to the possible status of the car.

With only four owners and the car having been 'local' you would think that there would be more info. available about the Car itself.

What are the dates and part numbers of the internal components like the ring and pinion of your rear axle housing and do all the proper COPO specific items exist?
