hi every one.a few days ago i found a lsd of an is200 sport.would it be possible to fit it 2 a is200 se?

Shouldnt be a problem in my opinion.

thought as much.i was thinkn about last nit while i was fixing the exhaust.any idea how hard it would be 2 change?

Should fit.

Shouldn't be too hard, if you know what your doing. If in any doubt though, take it to a Pro, shouldn't cost much.
