I too mounted my CB using the holes in the rearview mirror. It is great because you don't mess up the headliner. However, I extended the metal back and under the interior light. Again this did not mess up the headliner, and gives the bracket more strength. I can literally pull down on it with no problems. It is a convenient place for using the CB.

Good luck

See you out there,
