Not sure about the thickness or the hole size and spacing. anyone with one of these if you can, pls let me know the thickness of the metal and the hole size.

I really need a full size template, but don't want to bother anybody to do that. I figure I can just eye ball how it should look, but would like the correct hole size and gauge. I assume the crt neck cover is made from metal as well?
