I would also like to add, that you can replace the clutch plates and ramps in
the tran x diffs. The Tran x Brand has been sold to quaife and the guys who
used to make Tran x, are making there own version...which is only available
through Darrel at racetorations in the uk. I've not seen or used the new diffs
...as of yet.
