69 Camaro possible COPO?

[zeus]

I was wondering how to tell if you have a COPO car. I don't think I have one but might as well check. I have been told there may be a possibility. I was also told the vin is close to a couple of Berger and Jack Douglass COPO'S. The car is an original 4- speed car I don't have the original motor. Here is my trim tag:
ST69 12437 NOR336714 BDY

TR 711 59 B PNT

05C X44

Vin #124379N648262 It has multi-leaf rear springs, and a 12 bolt rear, When I bought the car I was given 2 tranny crossmembers.
