When I bought my ‘72 Supreme 20+ years ago this gauge along with a”blank” in the clock space. The “harmonica” connector looked original and unmolested. I suppose someone could have removed the tic-toc tach. BTW the tach wiring harness, including the braided coil wire are there. It just seems strange that the tach would be removed, when nothing else was. This is a highly optioned car, Dual Gate, Sport wheel, power windows.
