New in-dash tach clock replacment. Tach takes the position of the clock or clock delete plate for cars that never had rally gauges or tach - Features show quality metal housing & bezel, unlike the plastic and incorrect prior produced ones. This is 100% correct for 1965-67 GTO or LeMans models. Tachometers will work with factory GM points or factory HEI ignition. When using an aftermarket ignition system likes MSD, Accel, Patronix, ect. A lot of these systems generates higher output voltage to the tach lead than what a factory GM tach can handle. Factory GM tachs can operate on voltage ranging from 11.2 to 14.7 Most aftermarket ignition systems generate over 18 volts. You will need to buy from the manufacture of your ignition system an adapter to lower the voltage to the GM factory voltage.
