I came across this car on e-bay and he states the drive train is original to the car. It's a 12B and the engine is stamped V0913DZ. Could a December built car have a Sept. built engine?

Holly fender flares Batman, no vin number provided in the listing but if this is an early build then the partial vin number would be stamped on the pad, if a late built then down by the oil filter boss.
