Involves a bit of machining to take the full Ford Atlas clutch pack, IIRC, but others will be along shortly to either confirm or rubbish this!
That's for rebuilding the LS pack. If the diff itself is faulty, then that is a specialist job setting up clearances and preloads.

YEah involves machinging, for the Ford parts don't remember it being for Atlas but I can't remember what it was, and all those for parts will be interchangable any way. With the ford system you get two clutch plates instead of 1 so the lock up goes up to 40% I think. Not a cheap job though so if you don't really really want the extra lock up it may be cheaper to buy another diff.

ZF plates from mantas etc also do the job. Small bit of machining required. Had it done in the last sport, good fun!
