I believe RPO L78 listed in the center of the Buildsheet is Typical for a COPO 427 car.They were delivered with 427 engines installed,and have a 427 Suffix code call out in Box #27 on the same buildsheet as well.The Canadian Copies of the few cars I have here all show this too.
This seems Like a real Nice COPO Camaro,that is & can be Verified through Canadian Docs.
So why the Dual Ebay Auctions?
