Hi all
I am now lifing this part I change it when I re build the diff.
Tony did one National one test 8 packs of batteries. 2 club meets and a regional several meetings before I rebuilt the diff to give you an idea of the length of running.
This was all on high grip tracks in the UK.
I still use the same methord of building the diff as previous post I do not over tighten the screw before backing it off. Touch wood we have not snaped a screw for some time now. Hope that is not a Murry Walker
I found it was always the rear that went never the front.

Hope this helps.
