Speedway GM Manual Trans to Flathead V8 Adapter - GM Clutch

Now you can easily mount a modern, fully synchronized GM manual transmission to your early Ford or Mercury Flathead V8 engine! This is a great way to get better driveability and improved performance from your 1932-48 Ford or 1939-50 Mercury Flathead.

• For use with GM-style clutch fork and bearing (our part #916-2915)
• Recommended for use with Borg & Beck or diaphragm-style pressure plate
