Ralley dash lenses

The more you know.... This original fuel gauge is a source of chassis ground. The original amp gauges are fire cracker hot all over. If the top of the metal matting frame should fall against these 2 gauges, the needle in the fuel gauge will be cremated to a white powder ash in a millisecond. Can leave a burn scar on the screen too.
Back in their daily driver days, owners would learn this by tapping on the lens when a gauge stopped working.
Bottom line, you can't overdo anchoring these bezel pieces.
