1969 Copo Chevelle

[bdplvx]

I was doing some light reading and came across the following statement;

"According to Cunneen, it appears that only the 9566 options would have been used on non-Yenko orders. Yenko orders would have carried 9562, 9694 and 9737 codes". Is this 100% accurate?

I am 100% positive my dad's car came with ralley wheels (still have two of them) from the factory. I wonder if there were any COPO cars ordered with the 9737 option not delivered to Don? A couple other items I find interesting is that the car did not have any stripes or SYC markings of a Yenko car, however the vin number is within 13 cars between these other two Yenko cars as listed in the link below.

"Chevrolet built 86,307 SS Chevelles in 1969, and of that number, 323 were COPO cars. Of those elite 323, 99 were sent to Yenko to be transformed into a Yenko S/C Chevelle at his Canonsburg, Pennsylvania, dealership".

Does anyone know out of the 95 vin numbers on the list what the other 4 mystery vin's are to make up the total of 99?
