I've got an old Dynamo cut-corner style cabinet, and bought a replacement control panel on eBay - SFII layout, guy even punched a seventh "Neo Geo" button for me no problem.
So I take it over to my cabinet, line up the hinge, and try to close the panel.... THUNK!  It hits the sides!  Damn thing looks like it's about 1/8" too wide!  I should just be able to grind it down or something, but does anyone know anything about the differences in widths in seemingly identical Dynamo cut-corner style control panels?  I thought these Dynamo cabinets were all identical.
