You can do like me and buy a pre-owned large pumpkin bolted diff on eBay for your 6-speed manual. I paid $450 for it, got it shipped for free to HPA, HPA converted it to a Quaife LSD and shipped it to me in Canada ready to install on my car. I sold my welded 3.08 diff for $500 locally to recoup some of the costs...
Correct - you can find a bolted diff of of early 2007 335i's to serve as the core
