So i got my new diff from the diff doctor here in the ACT

Brand new borgwarner diff cut and shortened 35mm spline billet axels, 4.11 ratio, R31 disk's and calipers, braided lines, they have done an excellent job looks great just need to put it in makes the little h165 look like a kid's toy

It primed currently just needs to go to the powder coater next week

The leafmount seats are 980mm centre to centre and from hub to hub 1160mm total length

I will put up some pictures of the diff and brake setup soon along with a comparision sizing from the h165..

Next thing to do is get my yoke fixed up and new tailshaft shortned with a borgwarner 8 bolt uni :)
