I have not seen a COPO Chevelle build sheet with the 9562 number except for a Yenko but that does not mean that there were none. I would not say that all the COPO Chevelles used the 9566 number for two reasons. One reason is because a dealer like Berger, who knew about YenkoÃs COPO 9737 Sports Car Conversion, may have ordered it on some of the ten COPO Chevelles they sold and the build sheet for such a car may be a 9562xx 9737. The second reason I would not say that all the COPO Chevelles used the 9566 number is because I have heard that some COPO Chevelles came with steel wheels and small hub caps instead of the more common SS wheels. The steel wheel cars may have used COPO numbers 9562EA or 9562 FA which specified a different tire then the COPO 9566AA and the 9566BA.
