I also emailed this to them, but I figured someone here might know.
I just got 4 joysticks and some other assorted stuff from groovygamegear.com
The sticks (3 top fires and a 2,4,8-way switchable) seem nice, but they have a raised bezel on the base that is supposed to poke through the panel. Does anyone know offhand the size of that little bezel?
I figure if I can get an answer today then I will be able to stop at the hardware store on the way home and buy the correct holesaw needed to cut the hole. I already have the right right holesaws for buttons/standard joysticks, and 3" trackballs, but I know both of those are wrong for these sticks.
