all the 74 steering stuff will work, before you get rid of the bare frame get some measurements from the upper a-arm bolt through the frame (pass side)to the pass side mount of the steering linkage. I had to drill a couple new holes to mount mine.
I see you already have the capt fab steering bracket for the box, and all you have to do is shorten and get the column shaft welded, or if you like bolt on better, capt. has a piece for that as well.
another tip for the few holes that you have to oval out, I think there are 2 on the suspension, and 1 on the steering box:
get a piece of steel with the 25/64 hole in it , and clamp it to the frame over the hole that needs to be ovaled, use that piece as your drill bit guide oval out the hole.
