Although it is hard to guess the .whatever you can count the turns of
the driveshaft to the single rotation of wheel. I never got around to
it, but I ws going to mark the drive shaft (actually the shaft was off
the car) and the housing so that I could determine the degrees but it
appeared to be pretty close to 9:00 which would be close to the 3.7 on
the TR3. I have never really thought about it; but should both rear
wheels be up in the air to do this?

Subject: Guessing the Diff. Ratio
I am wondering if it is possible to figure out the differential
number of teeth on the ring gear without taking off the cover
counting. Can you jack up one rear wheel, put it in neutral and
wheel and see how many times the drive shaft rotates for each
rotation? Or do the planetary gears come into play? I would
if it was done on the r.h.s. it could be possible.
