Mameroom control panel/trackball question

[methodical]

I just received my 4-player control panel from Mameroom/North Coast Customs and I expected to find a cutout for the trackball assembly and holes for a mounting plate... but what I found was a 3 3/8" hole and 4 screw holes on the underside.

So, I'm a little confused. Is this some sort of error on their part? What are my options for mounting a trackball with what is there, without doing any woodwork as I haven't much skill in that area (hence ordering the CP from them).

Any help would be greatly appreciated.

it sounds like you have a flush/undermount setup. Have you contacted them about instructions or did they send any?

This type of setup is the most desirable to many because it looks the best on top.

They didn't send anything... I did email them about it but haven't gotten a response. It's only been a few hours though.

There's no space routed out for the trackball at all underneath. Just the hole. I'm a novice but it just seems impossible to mount a trackball there without routing out a space for the trackball assembly.

Will the GGG super high mount allow me to mount a trackball this way?
