Review on 🚙 Spare Tire CB Antenna Mount for Wrangler JK 2007-2018: Compatible with Rubicon, Unlimited, Sahara - 2/4 Door by Govindarajan Diepenbrock

You will probably have to modify it a bit so that the antenna clears the spare wheel. The hole for the CO-239 barrel needs to be moved a little closer to the end of the bracket towards the chassis. I cut mine with a dremel. Once this is done you will notice that the bracket is not completely level due to the plastic on the spare tire bracket. After installation, it tilts slightly towards the spare wheel. Hit the bracket with a hammer to open the corner a bit to fix this. When everything is ready, give it a coat of black engine paint and you're done.
