I agree with Charlie. I bet its original. I looked at a '69 Z with the engine build date within 1 week from engine assembly date to the car's final assembly date. I found it so hard to believe only because the supply chains of the 1960s were hardly just in time or lean. Ironically the car had a beautiful stamp. Nonetheless the car proved to be 100% legitimate. Same applies here...
