Rear disc swap Q's

[pennell]

I want to do a rear disc swap on my 88 316i. The only problem:
my rear end is a 4.27 small case, and the disc swap is from a car with a big case rear end. How can I make it work? The output flanges are different sizes; can I change them? Or can I just use half shafts from car...?

Hmmm... how is that possible? all halfshafts on e30 are interchangeable(minus the abs rings off course).

Things should just bolt on fine on your case.

Should work fine..I just put a big case diff into my small case 84 318 without changing anything

Alright, thanks for the heads up guys. It turns out my diff was a big case anyway.
