thank you Merc and Hallivand--we did locate the clip, and the new unit is on the way...
curious thing, though: since receiving the S420 three years ago, we've replaced the regulator apprx. once a year--but, al three times it was the right rear unit, which, in fact, does not get nearly the use of, say, the front passenger...
once the regulator was removed, we tried sliding the window up and down in the track a few times--to determine if it was binding in the tracks (white plastic?)...
it does seem a bit 'stiff' near the lower end, but there may be another issue causing the RR regulator syndrome...
we may try a lubricant on the track...
thanks again, Mate!
