Cut corner Dynamo with trackball?

[TOK]

My buddy wants to do a 2 player 6 button setup with a trackball in the middle. The cab is narrow, and right now he's leaning toward just fabricating a new panel. I thought I remembered seeing some examples of cut corner cabs with trackballs, but searched and can't find them.

He has a 3" Happs, and right now is leaning toward just abandoning the cut corner profile. Any pics/design ideas would be great.

Here's the backside of a Dynamo 25" cabinet panel made for 2 trackballs.

I just dropped a Capcom Bowling off at a buddies house that was in a cut-corner.  Trackball was mounted on the side, though.  I think I've got a couple in the garage with a 2 1/4" TB in the center, I'll check and get pics if they are.

I almost bought an Ameridarts cut-corner cabinet. It was missing the ball but had a 3" cut-out dead center. It looks like there's one on KLOV too.
