The Bronco and F150 tailshafts have a different end on them. The Bronco has a yolk that bolts to it. I made sure to undo the nut while it was still on the Bronco and hooked to the engine. Otherwise, I never would have been able to break the nut loose while it was on the ground.
As such, I'm putting the nut back on now and will tighten it once it's on the vehicle and bolted back up.
