COPO Identification

[JoeC]

Kurt,
I have to disagree with you again. There were some COPO Camaros built in LA and there were some COPO Chevelles built in Fremont, CA. No 1969 Yenko/COPO's were built in CA. as far as I know.
I think the confusion on X-codes- comes from the duplication in the parts used. The Style Trim Group has a parts list, the SS396 trim group has a different parts list but it shares some of the same parts. The RS trim Group has another parts list again sharing some parts as with the the rest of the X-codes. Using the rear fender louvres as an example - X44 (base car) has no louvers, X11 has louvers from the Style Trim Group parts list; X66 has louvers from the SS396 parts list: X22 got you 1 set of rear fender louvers but you "paid for" two sets because of the duplicated parts list. Did I add to the confusion? The people on the assemble lines must have mixed up a few.
My point on Yenko using the COPO forms is that he was able to get big block X44 cars without paying for the SS396 trim parts which went against the normal order methods.
