need plug for seat armrest hole

[DeWitt Harrison]

Sport seats from 1989-91 200s and others have a driver's
seat armrest bolted to the backrest. In some situations,
like installing such a seat into an earlier type 44 car, it
can be helpful to remove the armrest. This leaves a 32 mm
(1.25") round hole in the side of the backrest. It would
be nice to be able to cover the hole.

Has anyone found an attractive hole plug for this situation?
Does Audi make a part to do this job? (I can't find one in
the seat parts drawings.) TIA for any BTDT.
