My post wasn't intended to raise the possibility that this is a correct COPO car, but instead to draw attention to the possibility that the car <font color="red">
MAY </font> have a correct numbered and coded COPO/Yenko engine and trans in it.
IMO if the engine and trans were correct, someone out there may have the car they belong to.
In the ad, the guy states that the car is an X-33, Z-28 trim.
IMO, no question that the car ISN'T a COPO, but the motor and trans may be. Perhaps someone with a VIN list could take a peek and shed some additional light on the validity of the stampings and the partial VIN.
