Price: $1200 + shipping
Located: SF Bay Area
This is a freshly rebuilt 135i AT 188 carrier with the MFactory LSD inside.
Selling this as I went a different route and put a whole m3 rear end in.
I just got this back from MFactory on a fresh rebuild (heard some noises coming from it). Lifetime parts warranty is fully transferable to new owner so this is just the same as buying from MFactory except I don't want your OEM open diff or a core charge.
Located in SF Bay Area, willing to ship; diff is still in original packaging from MFactory after rebuild!
