Good idea, but it is all one piece. It has been suggested that you could have the proper bell welded on, but nobody has tried yet.

We looked into that when I had winmutt's tranny at Stu Ritter's shop. The internals between the W123 and W201 5-speeds are a completely different layout, nothing internal will directly swap between the two.

That's a shame!

Well, as bgkast said maybe cutting and welding will be the way to go. Forced, were the transmissions' housings too different? I mean, was the w201 housing bigger than the w123? My main concern is if there's enough room in the w123 body to fit the w201 transmission...

I have access to a w123 4-speed from a friend. I just need to start looking for a w201 5-speed. I think I might be able to get one from a 190D 2.2

Soon to be installed: Bilstein HD, R107 front discs and 4-piston calipers, HD Suspension springs, wagon front swaybar.

I was wondering if anyone has a link to a parts list for the 5-spd? I looked on the RU-Detail site. They show the parts for the shifter. I think they show the 4-spd manual tranny. It might help to cross reference parts and figure out what is different.

Yo---the hot ticket for this turbodiesel/5 speed swap according to the guy at eurotruck is to use the 107 clutch--is that a twincam 6 or the v8 clutch?
