Ford-O-Matic Pulse Generator Adapter from Classic Instruments

Classic Instruments now offers a speedometer drive adapter for ’51-56 Ford-O-Matic transmissions. Due to the unique speedometer drive arrangement found in those transmissions, connecting an aftermarket speedometer used to to be difficult. This adapter takes that special arrangement and converts it to the more common 7/8”-18 speedometer cable output to connect a mechanical cable or electronic sensor. The high-quality adapter is machined from steel and re-uses the original Ford-O-Matic drive gear for a simple installation.
