Cooked E46 M3 Diff - Buy 2nd hand, rebuild or new?

[slampis]

Hi M Dudes and Duderidas, I have a lovely e46 M3 which is nearly complete apart the boot floor and the diff - seems the bearing on one of the shafts is gone, and there was no oil inside at all when we discovered the diff is done, so I'm guessing it's pretty much done. I had a quick browse and it doesn't seem you can get a half decent second hand one, at least I haven't found one, so the question is do I refurbish or get a new unit? Any idea how much to refurbish and where and if I do refurbish, are there any must to mods to do at the same time?

Thx!

Thanks, I have experience with these people, not sure if I want to deal with them again

Anyone else using anyone else? There must be someone specialising in building these?

Perfect! Thank you! I will try to remember to report the outcome
