I don't see why your mad dude, just looking out for other forum members. Honestly good luck with the sale.
Now here is how to get everything done for under $1000.
BMW Motorsport gears: $804
Straight from Rahal BMW 742-746-2600.
$530 for the 3.91 (Part #184.108.40.2068.525)
$804 for the new edition 4.10 (Part #220.127.116.111.899)
Installing R&P: $85
Man up, get your hands dirty.
Fluid: $30 ($15 a quart)
Amsoil 75w140 Severe gear diff. lube.
you forgot that you have to buy shims and crush seals... if you want to do it yourself thats fine, but to fabricate a diff from just a ring/pinion, will take you 6-10 hours of labor.
because theres no way in heck you are buying a 4.10 fully built diff for $804.
