Re: Diff mod's Perth, WA
I'm assuming its a BW? I went to Diff Trans Specialists in Jolimont last year for an upgrade of 2.77 changed to 3.23 on a BW 4 pinion LSD. They did a good job - needed a new axle (31 spline), replaced all the bearings and tightened LSD cones up.
They did a good job, albeit a bit expensive. If its 9in you can't go past Dimmoff's in Malaga.
