Is it possible to remove the metal siderails on my pin? I just picked up a "Williams Widebody" playfield glass for my Judge Dredd, and it *just* fits inside the metal siderails, but those damned rubber channels are in the way. I'm assuming I got a piece of glass that was not in fact the right size... But for the time being, removing the rubber channels would leave enough room to put the glass in, or is that a bad idea?
