all i did to mount the trackball was cut a squarish hole in the underlying mdf the same size the modified tb base. then used metal strapping material(i call it plumbers tape, not sure if that's correct) as a bracket behind it to clamp it in place. it's sandwiched between the plex and the backstrapping. the art keeps anything from showing. it's nice and snug. there's a couple pics on the bottom of the first page that shows the bottom of the cp. the tb isn't the best, but works for windows and is ok for golden t.
the cp file should still be in layered format. just delete the ones that contain the button holes, and you should be good to go. the titles for the non-action buttons are also in layers so they can go as well. if you don't have a program like psp or adobe available or i screwed up the file when i posted it, just drop me a line and i'll make the adjustments and get the file to ya.
