1966 Buick Wildcat Tachometer 6000 RPM - slightly used tested by D&M Restoration
This is a unique 2 wire set up, with Coil and Ground. You do not run 12V to this Tachometer. It has the adjustable red line needle, and there is an adjustment screw in back to calibrate this tach (which we did just before testing). This is a very rare piece. Don't let is slip away!
