I am hesitant to post this because it makes me look like some kind of moron or lunatic. I raised the rear of the car and marked the position of the driveshaft and driven wheel. I rotated the driveshaft until the wheel made exactly one full rotation. I repeated this a number of times because I couldn't believe it-the ratio as close as I can measure it is 2.12:1 . This could explain why the car was missing the speedometer drive-someone was trying to do some sort of modification to it to make the speedometer read correctly. How in the world did someone come up with the parts to modify the differential in this way? Anybody out there have any ideas? Has anyone heard of something like this before?
