Well honestly, been working a couple different custom bezel ideas for about the last year. The original concept ended up being too much trouble to get consistent results. That concept was using a pair of 1963 New Yorker tail light bezels as gauge bezels . I spent a small fortune in silicone to made a set of molds from the pot metal tailight bezels. The molds turned out perfect. But the fiberglass resin idea that I tried to cast out of the molds proved to be very inconsistent. I would get HUGE air pockets between the layers and ultimately, the things would crack after a few weeks of temperature changes. Mainly cause they ended up being so dang thick. I finally got two of them to be workable, but then as I sat there looking at them, I realized they just were too large. the 8 in diameter didn’t look as good once the gauges were in.
