Standoff bushings for a new stereo installed the wife's 2500 RAM.
One of those new color LCD touch screen stereo's with GPS, Bluetooth, and rear camera.
They did not supply Delrin style spacers to mount the new head unit in the old stereo surround.
I was able to use the white 48"UHMW Polyethylene 1" round that another member turned us onto that was being sold for an outstanding price($15) on ebay. Was able to center drill and turn a long enough piece on the larger lathe and then cut into several different lengths that were needed. Worked great, Now if I could figure out why I can't get the supplied rear camera to work...
The UHMW round also worked for the rear camera mount since the center trailer ball hole was unused since the truck has a class V receiver already.
I turned the round down to an interference fit drilled screw holes in it and then tapped it in and mounted the camera. Funny I spent the most time of the whole install setting up and wiring the camera and running the cable. Oh well at least the blue tooth pairs and stereo works great with the DSP settings.
