Anyone know if you can further reduce the footprint of an Imperial trackball (the 2.25" one) by a half an inch or so by cutting the case or something similar? I'm trying to fit a trackball into my CP, but I JUST have about 4.75 inches available to fit the thing in, depth wise. I'd like to not totally mod the front supports for the CP in the cab I'm using, so I want it to fit into that space if possible.
