My under dash mount must have 12 or more holes in the flange to run screws,
so even if each screw could only support 1 lb (i suspect much more!) 12
shouldn't have any trouble. I've even considered the idea of drilling pilot
holes and actually tapping threads into the lower layer of glass, but I'll
probably just do the wood screw thing.
I guess thats how the dome light is secured now that I think about it.
