So I did an engine and tranny swap on my 325i. Now it has a tranny and engine from a 330i. I have a drive shaft for the 330i tranny and found out that it does not fit the 325i differential. I'm buying a 3.46 diff from a 330xi and im wondering if my 325i axles will fit the 3.46 diff from the 330xi. Please help. Any answers appreciated!!
