I have 7/8" dia. holes drilled in my wheel pants, but found a pair of black snap plugs in my junk bin that just fit those holes, sit almost flush, Have not fallen out, and the black does not stand out on my dark blue wheel pants. Made custom inflation chuck to reach down those holes by taking guts from cheap angled type and installing into piece of 5/8" dia. brass drilled and tapped to suit.
