I recently replaced my "new" '87 300D's wiper arm and blade with the shorter arm (124-820-43-44) and matching blade. On the old arm, the rivets were loose and the springs were weak, keeping the blade from making good contact with the windshield. The wiper works much better now.

However, the cover at the base of the old arm, above the round gearbox cover, doesn't fit the new arm. On the old cover, there is a screw to attach the cover to the arm from underneath, and a square panel you can lift to access the Allen-head screw to remove the arm. The new arm has no screw hole - it looks like the cover should just snap on to two metal "wings." Can someone with the EPC get me the part number for the new cover? I don't like driving around without it - it looks crummy, plus the shaft of the arm is exposed to the rain when the wiper extends.

Attached is a screen capture from one of the PDFs on the W124 CD. The cover I'm talking about is item number 1 in the picture.
