: Out of curiosity which which engines have the same attachments for the bell housing and clutch?
: Is it possible to swap boxes from an M20 to M30 car or vice versa? How about the M50/52?
An E34 12 valve manual gearbox will fit an E28 M20 engine but not the E34 24 valver.
The bell housing and the input shaft are different.
