Installing a Tach in a '64-66 Chevy Truck


hen '64-'66 truck owners get together and talk about rare factory options, several items are always up front in the conversation.  Factory air-conditioning, big back windows, and triple bucket seats are always on the list, but one of the rarest factory options available on the '64-'66 Chevrolet trucks was the in-dash tachometer.  Many people are misled into believing that the 5,000-rpm tachometer was only available in the C-40 and bigger trucks, but it could be ordered in the C/K-10 through 30 series as option RPO U16.
     Thankfully, now any gauge-style '64-'66 Chevrolet instrument cluster can be converted to a tach dash with this new reproduction kit from Early Classic Enterprises.  Installation is a basic bolt-in affair and requires only basic tools and skills to accomplish.  In less time than it takes to watch a few Saturday morning cartoons, you can upgrade your '64-'66 Chevy truck dash with one of the coolest options available.  Follow along as we show you how.


1.  After disconnecting the battery, the instrument cluster needs to be removed from the dash to access the rear of the housing.  The trim bezels for the headlights, wipers, choke, and ignition switch all need to be removed.  The headlight rod and knob are removed by first pulling the rod to the on position and by reaching under the dash and depressing the spring- loaded button found on top of the headlight switch itself.  Depressing the button allows the rod to slide out of the switch, and the bezel can now be removed.

The original dash in our donor truck is in reasonably good shape, and all of the instruments are in working order.
Because the lens is scratched and dull, a new one will be installed at the same time, along with a new outer bezel.


2.  GM offered two choices for windshield wipers in this era of trucks.  The standard setup was a single-speed wiper, and the knob was simply pressed onto the shaft of the wiper switch.  They also offered a three-speed wiper motor with a washer pump.  The deluxe wiper knob has a small set screw on the backside that holds it in place on the switch, and the washer button protrudes through the center of the knob.  The choke knob is threaded onto the shaft of the cable itself.  Removing both knobs allows the trim bezels to be unthreaded and removed.
