I once screwed a cb init in the same place where you are wanting to mount your screen. I bought a cb unit to use at Moab and screwed it in( 4 very small screw holes). Went to MOab...cb worked fine, Moab over, returned cb.
then had those ugly little screw holes....I'm sure you could improve how they looked, but they were still there.

I have learned to ignore them, but Everyone that gets in my VX or looks inside asks about them......aggggg... I am thinking about finding leather same or similar color and lining it.
