My understanding of these vehicles is that you actually WANT the diff slightly off centre. If the diff is directly in line with the gearbox output shaft, because the tailshaft is so short then the tail shaft will have very little (or even zero) angle, this in turn makes the uni's very straight, and they can wear out quickly like this. To compensate for the short tailshaft, offset the diff slightly to one side and this provides the angle in the unis to stop premature wear.

I don't know if this right, but is sounds plausible to me.

Baz: I think auto VE's use 2.92:1
