Comes complete with new gauges, tach, printed circuit board, lens and housing. This unit is for 1970 Chevelle and El Camino S.S models with floor shift. All gauges have green lettering. Tach has a 5500 red line. 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 Additional Information Note S.S. Dash Gauge Cluster, Green Lettering S.S.
