And here I am, late to the party again!

I did some serious soul-searching before I drilled the holes for the mount, but figured worse-case scenario I may have to repair them at some time, or, just leave the radio there. Not the end of the world either way. Ran the antenna wire back to the headache board, installed a bracket there for the whip. Only downside was I had to run a ground wire back to the cab just to insure a good ground.
In the first photo the white speckles on the headliner are reflections from the radio knobs. In the last image the antenna has been removed (quarter-twist) so it didn't get bent up going in the garage.
