[YENKO DEUCE REGISTRY]

Kurt/Pete;
I stand corrected, the A,B, or C, is not on the POP as I had thought.

My underlying quest with this post is to determine if GM changed COPO 9737 for the Canadian cars vs. the Yenko cars by putting the M21 into the Yenkos only?

On the Canadian documentation it lists COPO 9737AA, on Yenko's order form is lists COPO 9737CA - but Yenko was ordering 4speeds w/ power steering on this particular form, and I don't have his order form for 4speeds without p/s like the Canadian cars. I think the difference in the suffix letters pertains to the power steering?? or the M21 vs. the M20??? Any thoughts?

JoeC: You are correct with the deciphering of the '133' on the POP.
