If there end up being aftermarket gear sets let me know (and maybe I can save myself some effort)
This build is still in the planning stages. So I am asking now before I pull two transmissions apart.
Are there any differences in shaft diameter between the gear boxes, (or other differences for that matter) which would prevent me from swapping the 1st through 3rd from a F4W71B 4-speed to a later model 5-speed? (In short, are the gears compatible?) If there is already a post on this I apologize. I could not find anything searching, and the search function kept breaking itself.
