Diff is almost the same
it's a 7.5" LSD the same
but the output flanges are different
but it's only a circlip to remove and fit some cossie ones
then hey presto, low mileage diff from a low powered auto that is 10 times better than an un-re-built one from a sierra cossie that's been doing donuts and launches
with hindsight i shouldn't have sold it, should have put a t5 manual in (auto box was broken) and kept it. oh well
