    Product Description

    1978-1979 Corvette Tachometer Circuit Board - Late C3 Precision

    Restore the vital signs of your Late C3 Corvette with this high-performance replacement tachometer circuit board. Specifically engineered for 1978 to 1982 V8 models, this board is the definitive solution for fixing erratic needles, pegged gauges, or complete signal loss in your factory analog cluster.

    Vehicle Compatibility:

    • Model Years: 1978, 1979 Corvettes

    Engineered for Reliability:

    • Pre-Calibrated: Professionally bench-tested and calibrated for V8 accuracy. It arrives ready for a "plug-and-play" installation—no specialized calibration equipment required.
    • Enhanced Durability: Uses modern, automotive-grade solid-state components that are far more resistant to the heat and vibration of the Corvette cockpit than the original 40-year-old GM electronics.
    • Simplified Installation: Features pre-installed mounting hardware. This is a 100% bolt-on part; no soldering or spacers are necessary for a perfect fit.
    • Made in the USA: Manufactured to exacting standards to ensure your restoration meets or exceeds original factory performance.

    Fixes Common Cluster Symptoms:

    • Tachometer needle stuck at zero or fluctuating wildly.
    • Inaccurate RPM readings that don't match engine sound/performance.
    • Needle "pegging" to the maximum RPM as soon as the key is turned.

    Installation Support:
    Every board includes a detailed installation guide with high-resolution color photographs to assist you with the removal and replacement process.

    Return Policy:
    Electrical components are not eligible for return once the sealed anti-static packaging has been opened. Used, installed, or modified parts are non-returnable.

    Easy checkout and fast shipping
