keep one wheel on the ground, turn the other wheel two complete rotations, count the driveshaft revs - it's pretty hard to tell 2 rev from 1.95 [or 4 from 3.9 either really], so knowing the possibilities helps, the 59 might have had a 3.38 from the factory, that's when the option started, but the standard with a stick shift was 3.90 and with the OD it was 4.11
