Sorry I don't have anything more exciting, but I felt the need to post something here. Basically what I did was unscrew the oe antenna, took it to the hardware store to match the threads and picked up an allen head bolt and lock washer I found aesthetically pleasing. In hindsight a set screw would sit flush and look better, but meh. Looks fine to me and only cost me a dollar
If I had an unlimited budget I'd remove the whole base, patch the hole, wash rinse and repeat for the body side moldings as well, fix dents, and repaint, but oh well. At least I can dream.
