Antenna blank?
 

So, as many of you probably have the same issue, the gasket on the base of my antenna is gone. I've had the car in Arizona since I bought it and it disintegrated years ago. I don't listen to broadcast radio anyway, so I was wondering if anyone knew of a grommet or some kind of blank to fill the mount hole for the antenna after I remove it. I need to remove the headliner and find the source of a water leak that has ruined my key fob receiver and stereo and plan to remove it then.

I would measure the hole then stop by Ace Hardware. Is amazing the stuff they stock like that.

This is very true.
