I can confirm this: I have the PHS info for two '65 A bodies; one is 237375Z123456 and the other is 237375P123456. One Fremont car, one Pontiac car - same numeric portion of the VIN.

Very well stated and for the purposes of this discussion quite correct. I'd like to make one small modification just to be totally precise: not all sequence numbers started at 100001. In some plants (for some model years) 6 cylinder cars started with 600001. Also, when I worked at the truck plant Chevrolet trucks started at 100001 and GMC trucks started at 500001.

Not totally germaine to 68/69 GTOs but it does show that there can be different series of sequence numbers within the same plant.
