installing 78/79 F250 4wd steering box is the way to go. Welding and cutting a little of your cross member is required but its not all that hard. Here are some pictures showing the areas already cut out and the new metal waiting to be welded:

The F150 steering gearbox is completely different from the F250/350 box.
Not sure which one is better suited, but Jacob's conversion came out very clean. Was more work I think than he lets on about, but that's because he works his way through obstacles very quickly!
The 150/Bronco box mounts outside the frame rails, has a "standard" style pitman arm that faces forward and attaches to a long draglink that runs over to the passenger side.
The box is easily converted to "rear steer" where you can put the pitman arm facing rearward if that would work better. We do that on the Early Broncos all the time and it's referred to as the "4x4x2" box because you take the input section from a 2wd Ford gearbox and put it together with the 4wd box and sector shaft bits. Instant reverse-steer!
The 250/350 box mounts inside the frame rail, has the more unique pitman arm that faces outward to the driver's side and attaches via a short draglink to a "steering arm" bolted to the top of the steering knuckle.
