I made the time to work on my Explorer this weekend...Lets dive in.
2 things I needed to get accomplished: Mount F150 steering box and get front panhard bar installed.

I got the front pretty much mocked up (tacked) in place. This is the first swap of this type that I have ever done, I ENCOURAGE ANY AND ALL FEEDBACK IS MUCH APPRECIATED. Especially before I start to final weld everything in place.

PLEASE COMMENT.
Steering:
***Before I start on the install of the steering box. Its important that you pick up a oil filter relocation kit. Its a tight fit between the engine and frame.
Im going to talk mainly the steering shaft and the modifications I did to make this work. Unfortunately the Stock 93' F150 shaft wont mate to the 97 Explorer steering column. The box install has been touched by many others. ie:
@johnny499 Mountaineer thread was a huge help.
93' Ford F150 Shaft - there are 2 spot welds on each side of the shaft that need to be removed. You need the lower section/rag joint to mate to the steering box.
Stock 97' Ford Explorer Steering Shaft-
97' Ford Explorer Steering Shaft - Where to cut? there is a 'keyed' shape that matches F150 steering shaft.
F150 and Ford Explorer Shafts joined
Final completed shaft. Note that a large section of F150 shaft has been removed and spliced at the rag joint. I TIG welded the butt weld to ensure good penetration. This shaft still slips like the original Explorer shaft. Tight Space in there.
Steering Box installed - Clearance of final installation. Zero binding, smooth turning from inside. Sure is a great feeling to be at this point.
F150 Steering Box installed:
Added info. If you want to convert your pressure port to accept an AN6 type fitting, there is an adapter that you can pick up. The port has 1/2-20 threads in it (smaller port). (AN6 to 1/2-20 Inverted Flare) This adapter will allow you to have a standard high pressure hydraulic hose with AN6 fitting made for this application. Part number for adapter is FRA-491955.
You can take your stock Explorer hose (if in good condition) and have a 90 degree AN6 fitting crimped on at steering box side to mate the box to your stock power steering pump. Return line should be made easily.
