The;1964-66 Chevy truck direct-fit cluster features a speedometer, tachometer, fuel, oil, temperature, and volt gauges, and a 12V quartz clock decked out in one of four color schemes: black, tan, white, or Gray. Choose black for a near-stock appearance or select one of the other color options to match your project! The all-electric cluster with easy snap-in wiring harness arrives ready to install directly into the stock dash of 64-66 trucks; no cutting or alterations necessary. Perhaps the best install feature: the cluster includes Classic Instruments’ Zeus Speedometer Technology™ built right in which means no external control boxes. It is designed to re-use the factory dash bezel, bezel not included, to maintain the original styling of the vehicle, but has been upgraded with;bright LED lighting for even illumination and clear nighttime readability; light dimming control is built-in. Everything else needed to install the package is provided in the kit including a scratch-resistant acrylic lens and all necessary sending units.;No need to worry about fuel sending unit compatibility either, the cluster features a fuel sending unit selector switch to set it for compatibility with the existing/factory fuel sending unit, no new sending unit necessary.
