i want to run a better diff with my grey motor, i have an eh diff, and want to know whats required to fit it in..ie uni set up, tail shaft etc.

If you are only changing the diff centre to an EH one and not the complete drum to drum EH assembly then do this:-

Knock out rear grey motor uni joint and fit a red motor uni joint.Use red motor uni joint "U" bolts and nuts.

Pull out axles and the grey motor diff centre and fit EH centre ( will bolt straight in ) and refit axles.


Refill with diff oil and drive away, it's that simple.

What diff ratio is the EH one??..... 3.55 or 3.36 ??

I dont know if EH's had the 2 different splined axle types, but you need COURSE splines..

A.

They only had the course splines in original EH centres.

Holden changed to fine splines around the HX Holden ?? or thereabouts.
