We use a CB for communication in our local Miata club. After seeing what a magnetic CB mount can do to the paint on our Smurf Blue '91 there was no way I was going to put a magnetic mount CB base on the trunk of the LO MSM. I had some scrap metal laying around as well as a long bolt, some nuts, and some o-rings so I welded up a quick rig one day before an upcoming trip to Deals Gap. It may not look very fancy but it does do the job. I'm sure I could get much better reception with a magnetic base but I would rather keep the car looking nice. The mount works and CB range isn't too bad.

I pulled out one of the Frankenstein bolts and screwed my new mount into the threads. I made sure to put a rubber o-ring over the threads so it was sealed against the metal body.
