Hi Doug,
If you have access to a lathe, you can make them for about 25 cents each......I left about 1/16 inch gap between the bar and the grommet. The grommets are glued to the body with clear silicone, then a bead gets run in the bar to grommet gap. It's a cleaner look than you get with the rubber ones, which is what I was after. (Also helps justify owning a lathe
