8.5 from a Grand National will also work correct?
Not sure on the axle tube length and where the brakes end up but I'm hoping they're very similar so the wheels don't change their spacing.

I have a GN and I was thinking of getting a Moser for it so I'll pass down the 8 5 to my GTO and build it to 30 spline, hardened 3.90 gears, TA Cover and Tru Trac.

What are 8 2" Nodular, 3.55 rear ends going for us?
