Classic Instruments OE Style G-Body Instrument Cluster - CH78OE

Fits 1978-1988 Chevrolet El Camino/Malibu/Monte Carlo and GMC Caballero - w/o Gear Indicator

Part Number: CH78OE

Bring your 1978–88 G-Body back to life with an all-electric, OE-style cluster that installs cleanly and reads accurately. This direct-fit package includes a speedometer, tachometer, clock, and fuel, oil, temp, and volt gauges with Hybrid LED Lighting that blends perimeter glow with back-lighting for even illumination and excellent nighttime visibility. Turn signals and high-beam indicators remain in the stock locations to preserve factory ergonomics. The kit ships with a model-specific harness, push-button speedometer calibration, new acrylic lens, and a built-in ECM signal filter switch. Classic Instruments’ ZST™ (Zeus Speedometer Technology) is integrated—no external control boxes—so it works directly with ECM or VSS signals. The fuel gauge features a rear-mounted selector switch to match most factory senders or Classic Instruments senders. Use your existing diffuser for a factory-true finish.
