Try this:

170-760-04-62-7E8 bezel, there are right and left ones. You may find the Mercedes number on the back side. I found it it in the lock and hardware category. Probably better to find one at a local junk yard. The silver handle part is a different number than the black bezel.

Are you sure the cable has not come undone, or fallen out of it's brackets as it leads aft towards the outer door handle? That is not unusual.
