Here you go!
Keep in mind this hole has a little metal bracket in it for the screw that goes in it. So it's more like .20
This bottom hole, I shaped it like a funnel so the wire could move around when pivoting. It's similar to the new mirror bracket, but new mirror bracket was a lot more hollow.
This is the top of the hole in ball. It too is funneled just a little bit. Beveled I should say.
