Missing small part

[ZBTstang]

Its getting to be nice out again, I can actually get out and start working on and detailing the jeep again

However im missing a small part that im looking to find.
The rubber gasket that sits between the jeep frame and the arm that the soft top screws into (the removable piece thats shaped like an L and folds in the middle). If you look at the arm there is a metal pin that connects into the frame and a rubber gasket, well im missing the rubber gasket on the drivers side, even though this sounds like no big deal it makes that arm rattle like crazy when im driving with the top up and windows or doors off. If anyone knows where I can pick up such a small thing, please let me know.

P.S. its the rubber gasket that connects to the body frame, not the windshield
