Reference Details
- Common issue
- A claim that an X-code, SS-style body code, VIN format, or restamped drivetrain partial VIN alone authenticates a ZL1 COPO car.
- Confidence
- documented
- Correct value
- VIN and Fisher cowl-tag codes can support inspection but do not, by themselves, prove COPO 9560 ZL1 identity; documented COPO bodies may carry X11/X44 and some early X22/X66 codes.
- Where to check
- Main VIN plate, hidden body partial VINs, Fisher cowl tag X-code area on Norwood cars, engine/transmission partial VINs, and matching factory/dealer/registry paperwork.
