I understood that all vehicles 1968 and after had to have the partial VIN number stamped on the front of the block where you noted in your thumbnail above.Perhaps not all block manufacturing plants got up to speed as fast as others. The car DATA PLATE indicates the car was assembled in Fremont Calif but who knows where the block was manufactured. Interestingly, the M-40 trans has the correct partial VIN stamped on it. I guess I'll just keep looking elsewhere on the block . If I find it I'll let you know .
