It's designed for an s13 with open diff so the original shafts fit straight in.

It's a straight copy of a Quaiffe lsd.

I've read that you need to replace the belleville springs in the obx cos they are crap but I've had no problems with mine and I'm running more than 300bhp.
I like it as a road use lsd as you really won't notice it's there unless you are giving it the loud pedal.

So are you running both original S12 shafts with this diff? Or the two short S12 shafts?

They'd be the original shafts

I thought I'd best check before I start thinking of raiding the piggy bank

Me 2! Must admit that it would be easier just buying the OBX and some side bearings and then dropping it in.
Only problem is do I replace the other pinion bearings to make sure they dont give up once on the road. This would mean a whole load of hassle according to the Manual.
In the meantime I have sent an email to RHDJAPAN.com to enquire on the prices of the bearings
