6-speed***

I found the transmission from a c320, haven't bought it yet but will be picking it up along with the pedal assembly and slave cylinder etc next week at some point if it's still available.

From what I've read so far it has direct bolt on compatibility to the M104.

Has anyone done this before?
Is there anything else I will need?
Will the drive shaft line up?
Will I need to change computers?

Any tips and advice will be greatly appreciated.

I have a 94 wagon but might be trading it for a 91 coupe. The m103 has the same bell housing pattern right?
