Good used working power window regulator as shown. Pretty straight with minimal teeth wear. These are getting very hard to find for the early 123’s. You should pick up one for a spare. This will NOT fit the 300CD or 280CE coupes.
Fits 123 driver front door 1977 to 1980 240D 300D 280E and 300TD wagon
