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&rsquo, Zeus Speedometer Technology&trade, built right in which means no external control boxes.
