Just a little tip for those like me who can't stand a rattle in the cab of your truck. My cup holders in my console annoy me when my coke can is empty, plus a lip balm or loose change rolling around on starts and stops. I took a sheet of dark gray felt 1/8" thick and cut my patterns out to fit the bottom of the holders and the inside tray of the console. Put a lil glue down and stick your felt in and no more rattles of stuff sliding around. Cost is a couple of dollars, and 30 minutes. Simple but effective.
