40mm bearings, 90-91 Si?

[Jon Nelson]

Hello all;

Quaife has ATB diffs for special price, but the description says "except SOME 90-91 Si's" Both my transmissions are 90-91, is there an EASY way to confirm the bearing size with tearing into the tranny? My shop is full of ice racer.

Hi Jon,

I just bought a Quaife for my 1991 SI. It went into my spare tranny that I got from a 1990 SI and that one had 40mm bearings, so I was stoked on the price.

There is no way to be sure until you open up the tranny and measure them for yourself. BTW, Quaife offered to sell me the 35mm unit for $775, so either way, the price is better than the usual $895
