automatic e34 differential question

[liquidtiger720]

hi.
Well, since my differential needs new seals, gaskets, and probly other little stuff i was wondering how much it would cost to buy a new/used differential.
1. where could i look to find new or used e34 differentials (open and/or limited slip)?
2. how much would it cost?
3. what ratio would you get?


TIA


edit, oh yea, car is an automatic, so right now i have a 4.10 open differential. was quoted $330 for 2 seals and gasket insall.

I've seen Diff's on average for about $900, u can probably get a used one for cheaper. All E34's in Canada came with the winter sports package, they have LSD, my diff is a 4.27 (92 535i). So that might be something you might wanna pick up.

do you guys think the extra cost for a LSD is worth it?

edit: how come http://www.bmwe34.net/e34main/upgrade/Recipe.htm shows that i have a 3.23 diff ratio?
