Any application where the line was running too fast or the guys were too lazy to remove the now-included-with-the-assembled-engine alternator, stamp the VIN, and replace said alternator. We've had at least one '70 LS6 Chevelle and I think a '70 396/350HP A/C car where this was the case, where the VIN was stamped on the rough cast surface near the oil filter. I'm afraid I didn't record the assembly plants or dates for posterity.
