Another Tranny ? 4 u all

Will the bronco M5R2 fit in a 4wd 91 F150? I found out that the F150 used a Mazda transmission.. which years and which vehicles did the original, and M5R2 transmission also go in? because if it fits I want to find one of those trannies and throw it in my truck... unfortunately 1st and 2nd aren't working at the moment ;-)
