"release bearing guide O-ring"

[auditude at cox.net]

Hey,

This is the seal I mail ordered but couldn't find a home for.  Anyone know what it could be?

"Vehicle: 1991 Audi 200 QT 20V
Part: Rel. Brg. Guide O-Ring
Tube (56.8x2.6mm)"

$1.74

I didn't know I was going to be emailing, so I didn't take note of an OEM part number on the baggy it came in.  That could be one way to check I suppose.

It's a big thin donut with a round profile, and is gray in color.

Later,

Ken
