I have been searching all day and can not find any information that helps me out. I have a m52b52 (1998 323ic) in a m3 with the m52 getrag transmission. My problem is the transmission flange is small and the m3 drive shaft is large. What Falnge do I need? Can it come from a ZF? If your wondering why I am putting that combo into an m3 it's because the drive train from m3 was used in an e30 swap and I had a m52 swap sitting there so why not out it in the car and sell the m3. All help is appreciated.
