Nope, not that easy. 78-79 dana 44's are wider than the early bronco dana 44.
I run 76 F150 knuckles on mine (which would be the same as a 78-79 Bronco knuckle). As mentioned earlier, you'd have to address the steering with either the tie rod end bushings / sleeves, or changing up the tie rod entirely.
FWIW, I went to a tie rod over setup and used GM 1 ton tie rod ends on mine.
