Those pictures are zero help, you are correct. I’m not sure what part I need now. I may have to dig into the door and see if anything has a part number on it. I’ll post some pics later today of the problem.

Item 26 on RealOEM is listed as “rubber buffer”. Maybe that is the piece that is deteriorating. Although I kind of doubt it based on the fact that it’s only $1.10.
