In any case it is a randomly assigned digit to fill that spot so that one can't arbitrarily re-create a VIN after the fact. (You have to know the specific check digit in order to know the accurate full VIN).

V = Pontiac Michigan (South Blvd, as opposed to Opdyke Rd Light Duty, which started with GMT400, or headquarters at Montcalm/Joslyn, which was passenger car only).

Question: Was Opdyke Road sometims called 'Pontiac East'? I thought they built medium duty conventionals there from 1973 to 1984 or so. Thanks!
