Quoted from slochar:
Looks like the bottom plate's already drilled although probably not tapped to move the switches to the bottom to save space.
I’m betting those holes on the bottom of the drop are tapped. The ones in my Sterns are tapped.
One of the drops on my Dragonfist has the switches located to the bottom. They have never given me trouble.
When I get Nine Ball back together I am going to locate the switches on the bottom for easier servicing and adjustment.
It is good way to get the switches out of the way, too.
