el.FH rear retrofitted – are there covers for the crank holes in the door boards?

Hello Audianer! I refitted my el.FH back and used my old door boards again. Now, of course, I have a hole in the door board, where the crank was in before it is now a hole – is clear! I have heard, and it also knows that there are covers for these “egg-shaped holes”. My question Where do I get these covers or “clipse” from? Is this in the parts trade? Which part number do they have? I would be very grateful if that could tell me. Here in the For I have also seen an Audi that had installed these covers .. only I don’t know who that was anymore … Thank you very much! Joe
