Its the factory gauge bezel, it has to be cut and the aftermarket gauges fitted into it. It's a pretty labor intensive affair. That factory plastic makes some really memorable smells when you start grinding and cutting them.
Cutting the factory bezel out produces an interesting smell and smoke that I hope I won’t have to pay for later. It takes a brave soul to start hacking up your classic muscle car but in my case, my car is made up of a half dozen other cars and the entire cluster was dead save for the fuel gauge which o my read the first 6 gallons of gas.
