Well, the idea of using W114 parts is out.

W114 bolt, spacer and lock assembly.


W126 mounting bushing, dis-assembled.


W126 sort of assembled.


Where the mount fits.


Wear from the loose mount.


I suppose this is probably listed as a "non serviceable" part but I can't see spending $80-100 to replace the entire regulator for $0.10 worth of plastic. The window operates with no glitches with the exception of the movement caused by the elongated mount hole, the teeth are good and the slide has been recently replaced.

I guess I'll rebuild the inner bushing, epoxy the plastic halves together and re-assemble the mount.

You gents might want to rethink your claims regarding "metal to metal" contact on your mounts. I have never seen an electric door window which doesn't have a shock absorbing material in its system.
