I agree with you Motown! And, my sharing the fact that the later cars would have recieved the "C-1" paint code by the time this car was ordered, assembled, etc....
As for 70 COPO, I personally have no knowledge of where the latter car was ordered thru whatsoever, but I would find it interesting to read those documents that help support where that car was processed thru. As I am not the authority on the aj car, were you pretty sure it was to be with that group assembled for delivery to Canada at that time back then? I am curious to know and would be of good historical knowledge to share here..
