I put in a 140 MPH spedometer on the 100-M before thinking through the fact
that the 140 speedometer is geared for 1120 turns per mile and the 120 mph
unit is geared for 1325. Does anyone know a source for a different angle drive
that would compensate for the 17% difference. I want to keep this in the car
(it is NOS from Nissongers with 646 miles on it), but having just received by
first speedometer calibration from the connecticut State Police @ $240, I am
going to have to straighten this out, either with a new angle drive or by
memorizing a lot of odd numbers on the tach.
