Our 1966 - 1967 GTO direct-fit package is an all-electric cluster featuring a speedometer and tachometer with two dual gauges reading fuel/oil and temp/volts. It has green LED turn signal indicator(s), and a blue high beam indicator in the dash housing. Mounting hardware and a wiring harness are included to install with the original bezel, diffuser, and lens; setup is a breeze with push-button speedometer calibration and a built-in ECM signal filter switch. Includes all necessary sending units with a Classic Instruments LS sending unit kit, no fuel-sending unit. The fuel gauge is calibrated to 0-90 ohms. Save space with Classic Instruments' Zeus Speedometer Technology built-in, meaning the cluster requires no external control boxes and works directly with ECM or VSS signals. **Dash bezel and lens not included (uses original bezel and lens)
