Diffs - easy - make a mark on the input shaft and one of the output shafts, rotate the input shaft, count how many rotations of the input to one rotation of the output. If i have that wrong do it the other way round.
Diff ratios are usually 3.63, 3.91, 4.10, 4.45 - someone will correct me if i have them wrong

E30 diffs can also be 3.15, 3.25 and 3.45

Didn't know there was a 4.45...what was that fitted to?
