no the rs2000 diff is different m8
all the mondy stuff as been removed from ford service was looking at the two set ups on the computers at work
best bet is to have a word with bernie at cts gearbox man he might be able to re build the lsd diff for you or get bits for it off quaife

ps make sure your running the right oil for the diff to should be for lsd think its the same as the escort cossies
