I thank you all for your help in the matter! The sizes mentioned above are ones I had found before from internet searching, but the person who posted them wasn't sure about it. I too matched sizes to picture with the coin slots I got off of eBay, but that was way after built my box. I patterned mine from some Star Wars reference magazine from the 80's and again, was pretty badly off! The only measurement I need now is the thickness of the box, not including the switches, buttons, etc.
