ok so i aquired a medium case 4.10 lsd and i assumed it would bolt right up well i guess i was mistaken. I have posted on bimmer forums but didn't get much help just more questions. I tryed to bolt the diff up and everything lines up except the drive shaft seems to be to long about 10mm. I have a 325e driveshaft laying around. I know the car had a medium case in it before it was killed so would the 325 drive shaft work? i was also told the driveshafts are ajustable but when i looked at it ajusting it would through the u joints all outta alignment. Any help would be greatlly apreciated auto cross season is in two weeks and i'm tired of pegleggin it around haha.

I recently did the same swap without any adjusting of the driveshaft needed. From what I have read there is a collar on the driveshaft that needs loosened to shorten it. Do a search here because someone just had the same problem as you. Good luck.

It should bolt right in. Is the slip joint fully compressed and it's still 10mm too long?
