These parts are a set of BEAUTIFUL repro parts made by our very own @Stan, but not needed anymore.
for sale at same price as Stan is selling them, only this time they are located in the Netherlands.
The part is located at the top of the e9 armrest on the inside of the door panel; It prevents scratches on the wood part from the rigid plastic top piece of the armrest.
Some more info from the Meister-of-reproduction-parts himself here:
FS: arm rest gasket "ears"
These flexible seals are what prevents the top of your armrest from scratching the wood trim on the door. They come as a set, right and left. They can be painted with SEM to match your interior. They look kinda like ears... $40.00 a pair from 03857 New Hampshire.

Inside information is that only 2 sets remain available worldwide: this one and one in Stan's garage.
