Hydratrak the same as used in Holdens?

[TerryS]

Guys I am looking to upgrade the Hydratrak diff in my Holden HSV and was wondering if anyone knows if it is the exact same unit used in TVR's?

Any help greatly appreciated.

no it's not. The holden diff mounts with 4 bolts through the rear cross member into the top of the diff and a big rubber mount onto the rear off the diff. The TVR unit is all mounted with rubber bushes in completely different places. The internals a quite different too. KAAZ do new diff centers to fit into the Holden casing. part number DAG3810 is the one you need IIRC.
