Do I need an adaptor for this?
Did Ford put out a three-speed overdrive manual transmission in 1959? What would it take to bolt it up to a 428cid engine that I have.
I know I would have to install a clutch pedal and linkage and I most likely would have to change the speedo gears in the transmission.
Yes, Ford did offer a three-speed manual gearbox with overdrive as an option in the 1959 Galaxie and various other vehicles. Depending on the specific transmission you wish to install, you will most likely need an adapter to mountit to your 428 cid engine. Contact Bendtsen’s (transmissionadapters.com) for an adapter. Whether you need to change the speedometer gears in the transmission depends on what gears you need and what gears you have.
