... installed the new plastic part, today. The original is rubber.

I did a Google search for that recall number including the NHTSA database, but came up blank, searching under 300 series models

I still can't believe that 126s and 201s with M103 engines were not included in the recall, assuming that's the case, but I never got a recall notice.

The only '88 190E recall listed was the one about replacing the parking brake lever cover.
