Is a 91-92 year on a J reg 3.0 turbo diff one I need for my 3dr Cosworth plZ thanks in advance also it has 110k miles on it??

 

I don't know, try mk Motorsport or mt. My one is a 3.9 but that was a non turbo car.

Bara Singh at Bara Motorsport may be able to tell you and he can rebuild it with bearings, seals and weir kit for better locking.
If the price is low enough I would buy it anyway for the case.

 

Ok thanks mate

 

I rang bara an had a good chat an all sorted now so thanks!
