As valiant67 stated. Back in the day; quite a few F's had factory 4 speeds albeit with top gear being overdrive but, the tranny hump, pedals and linkage don't know the difference. Where you may get in trouble is finding V8 specific parts i.e. bellhousing and clutch linkage but I suspect A/B body stuff will work.

Yeah the only real external difference is the 3/4 lever is flipped, 4th gear remains 1:1 but becomes 3rd gear due to the reversed lever then the old 3rd gear becomes OD.

Correct me if I'm wrong but; weren't the OD vehicle bellhousings different (larger hole) to accommodate a bigger front tranny bearing/seal 'retainer', the exact name of that piece escapes me at the moment.
