Tony,
If your looking for more calibration numbers, I have a few. 1120 turns/mile
came out of a '74 '6 (3.7 diff) with OD. I think it is original. 1000
turns/mile can out of a '76 '6 (3.7 diff), no OD, defiantly NOT original. In
fact, I cannot come up with a car this would have come out of.
This was a topic of discussion on the list 6-9 months ago, you might check the
annals of time to gather more info.
BTW, The numbers on the face are probably decals, remember your old model
building days?
