Could someone please submit the control panel base dimensions for the Ultimate Arcade Cabinet II. I am going to begin my 2 Player with Trackball CP and may work off the UAII plans in the future for my cabinet, so I would like my CP box to be large enough to sit comfortably in the UAII if that occasion was to ever arise. What is the maximum people recommend the CP box overhangs the cabinet (not the overhanging top panel of the CP, but the actual box itself)?
