66 cuda tach can location

Those tachs, SW or not, are pitiful performers. They look great and are worth $$$ but are slow to respond and are mounted down by your left knee where you can barely see them. They dont work with aftermarket ignitions but the bezel can be back filled with a Sun "Super Tach 2" just get yourself some flat black paint and spray mask the Sun writing on the bottom. Whats in the can anyway? I sold my setup years ago, Ehrenberg was selling his can at the same time.
