I have a manual transmission with Overdrive from a 1965 F150. It is a heavy-duty 3-speed, with a rugged Borg-Warner T18 with an R-11 overdrive. Was optional for that year thru 1971 from what I researched. Used a 2 piece drive shaft. $275
Also have a '64 Galaxie 500 Cruise-O-Matic transmission. Matched to a a 260 or 289. Removed several years ago and stored inside. $125 See other listing.
Can supply picture on request. Email through CL if questions
