Sort of fits. The tail housing is different, and would need to be swapped out.

I actually put one of these in my 1993 w124. It's not that tough of a job, but you need the correct thin wall socket to get the nut off the shaft to pull the yoke and tail housing, swap over the speedo drive and put it all back together.

The transmission mount is different between the two series (w124 and w210) but swapping the tail housing fixes that problem. Otherwise the transmission is the same.
