Ford Speedometer Adapter

The NEW VINTAGE USA Ford Speedometer Adapter (Part No. 99002-04) is a precision aluminum sender adapter engineered to convert GM-style cable speedometer signals to Ford transmission applications. This adapter bridges the compatibility gap between GM and Ford drivetrains, allowing custom engine swaps, transmission conversions, and vintage restorations to retain functional speedometer operation without custom wiring or gauge clusters.

Constructed from natural aluminum, the adapter maintains the reliability of cable-driven speedometer systems while adapting sender output to Ford-compatible specifications. The compact 1.6 x 1.45 x 3.25-inch footprint and lightweight 0.17-pound design make installation straightforward without adding bulk to the transmission housing. Cable-to-transmission configuration ensures direct mechanical signal transfer, eliminating electronic sensor complications and voltage-matching issues common in multi-platform conversions.

This adapter is essential for hot rodders, engine swap specialists, and restoration professionals working with mixed-platform powertrains. Whether swapping a GM engine into a Ford chassis, upgrading a vintage speedometer system, or implementing a complete drivetrain conversion, this speedometer adapter eliminates the guesswork of signal compatibility. Vehicle builders rely on transmission adapters like this to maintain period-correct gauge operation while modernizing under-hood specifications.

Each unit is manufactured to OEM tolerances, ensuring secure fitment and consistent signal output across varying RPM ranges. The natural aluminum finish provides corrosion resistance typical of adapter-quality materials. Part number 99002-04 has become a standard reference in the custom automotive community for reliable, hassle-free GM-to-Ford speedometer conversion solutions.
