It was for a ‘66 Mustang, not a Fairlane, but many years ago I helped my friend change his car to a cable throttle. He had installed a Edelbrock Torker 289 intake with the twisted carb pad. If I remember we sourced the throttle cable, mount & pedal from a ‘65-‘67 Galaxie. Too long ago to remember all the details, but it worked just fine. Not sure if you have access to anything similar, back then that stuff was easily found in any salvage yard. I would think anything similar that bolts the pivot to the firewall would work.
