Thanks, rebl, ill pass this info forward.
your friend last time i checked was going to get quotes on installing a diff. make sure if hes buying the parts from rahal at BMW that he clarifies that he has only the ring and pinion.. the charge for building a diff from a ring/pinion is about $1000+ including other parts

the charge for swapping in a fully built diff, is probably somewhere around 300.

and lets just say that this is not something you wanna do buy yourself unless you know what youre doing.
