Dakota Digital RTX-68C-VET-X 68-77 Chevy Corvette RTX Instruments

The Dakota Digital RTX-68C-VET-X instrument system is a modern, bolt-in gauge upgrade designed specifically for 1968–1977 Chevy Corvette (C3) models. It preserves the classic factory appearance by reusing the original front bezels and rear housings while integrating advanced electronics, new lenses, and twin TFT digital displays. This allows owners to maintain an OEM-style look while benefiting from modern functionality, including compatibility with late-model drivetrains.

Part of Dakota Digital’s RTX series, this system emphasizes a stock-style design with contemporary performance features. The layout, face styling, and indicators closely mirror original equipment, but LED backlighting and customizable color options reveal its modern capabilities. Inside, CNC-machined housings contain high-quality, in-house-built electronics controlled by a central module, simplifying installation and setup.

The system combines analog gauges (speedometer, tachometer, oil pressure, temperature, fuel, and voltage) with fully configurable digital TFT message centers. These displays provide everything from odometer and trip data to performance metrics such as 0–60 times and quarter-mile stats. Additional built-in indicators and programmable warning lights enhance usability, while broad compatibility supports both classic and newer vehicle systems.

Lighting and customization are standout features. Users can choose from over 30 color options, 12 preset themes, and adjustable brightness levels for day and night driving. Full LED RGB backlighting ensures clear visibility and allows drivers to personalize the look—from factory-correct styling to bold, modern aesthetics.
