An 8000 RPM 'STANDARD TACH' for 67 through 70 Cougars.
This is the tach that Mercury should have made!

1969-1970 Non-XR7 version

This tach is a direct replacement for the clock delete. Just bolt it in, connect 3 wires & you're done.
My tach's work with points, Petronix conversions, Duraspark ignitions, MSD boxes (w/o an adapter!) - virtually any ignition system.


Interested in an upgraded 6000 or 8000 RPM tachometer? Contact me on TheCurb.org, Mercurycougar.net or at RCCInnovations.com
