I would agree with William and have never seen a documented California built COPO Camaro. I have seen quite a few California cloned COPOs. I believe that Jim Mattison did say, in his 1998 'Muscle Car Review' interview that some California COPOs were built.

I do remember at least two magazine feature COPO Camaros that were claimed to be real California COPOs. One was a high point restoration, Hugger Orange, single COPO and located in Florida at the time.

Does anyone on the list know these Camaros?

There is however a documented Fremont California Built Black/Black California COPO Chevelle.

Does your California Camaro have its build sheet on top of the gas tank? This would be very helpful, to say the least.

Your rear end tube dates, cast dates and internal components would be a key piece of the puzzle.
