ctfortner,
The information that I have obtained is detailed here

The cheapest way is usually the most expensive way. A steering box change is a very complicated thing. you need to get the input shaft and pitman spline very close to original. And have a pitman arm fit the spline and idler arm with the same lenght and bend. your working in three dimentions and it's easy to introduce all kinds of steering woes.

Grizzly, I know what you mean about cheapest. But I say that about this situation only because the Granada swap has been a proven success in the 56 Ford car, and of the options I am presented, it is the cheapest, by far. If it wasnt already tested by many and used for years, then I agree it may be the most expensive in trial and error and parts to make it work. I wouldnt attempt this by myself as I have never done something like this, but I am fortunate to have a good friend that really knows what he's doing helping me out.
I actually bought this granada stuff from a guy on here (nite owl) that has been happily running the same setup on his car for a couple of years. He had an extra set. He is running the factory gear box, so the only thing I am going to do different than him and most others is see if the Granada gear box can be easily worked in place of mine, since I am already swapping columns anyway. There is a guy on the hamb with a 57 ford that put the granada gear box on his with the granada p/s setup and said it was simple and works like a dream. Changed the lock to lock from 5+ to about 3.5.
What I can tell so far is the 2 gear boxes are pretty close in dimensions. Looks like the 56 box is just a tad longer but the Granada box looks a little beefier. I can say that when mounted to the frame though, the Granada box will allow about 1/8" or more extra clearance between the box and motor, which is a bonus. We are going to measure, mark, take pictures, etc and then remove the 56 box and put on the Granada box, since 2 of the 3 bolt holes appear they will line up. Once there see what changes would have to be made if any to make it work. The swap is done by leaving the factory box in place and putting the Granada pitman arm on the 56 box, install the granada tie rods, idler arm and center link, mount the ram and run hoses and pump, etc.
So we should (hopefully) be able to mount the Granada gear box so that it ends up sitting with the pitman arm located in the same position it would have if installed on the 56 box and see if that is acceptable for the input shaft and the rest.
I will know a lot more tonight, me and a buddy will be working on this for several hours tonight.
In case you havent seen the info on this swap, here it is
