DISCLAIMER: I've never really done any welding or cutting or fabbing, so the pics to come of my welds and cuts WILL look horrible.
Looking good I like your plans but I might add a few things about "the thrasher":
It should already have a hydro ready PS box at least it did when I sold it. Remember when you transfer the box to mount it as far forward on the frame as you can you may have to cut some sheet metal.
The tranny is a G52 not a W56 ie forward shift front box. But it should still work for you.
As has been mentioned I would definately keep it as low as possible and do 35's they will be plenty for most trails and over kill for most expo stuff.
Depending on how much extreme to expo type stuff you may want to trade the front welded diff for an open or more preferable selectable locker. I thought having a welded front end made things really annoying at times...
And definitely do not bob it. You'll want the room I promise!
So the ps box on the thrasher is already drilled and tapped? that would be great!

When I did did the axle swap on my 86 I installed High Steer with the stock steering box in the stock location and it worked just fine.I forgot that the runner already had the right box because it is post 85 I'm not sure exactly how it is set up, but when you swap to crossover steering on a pre 85 it is important to push the box as far forward as possible. I imagine there is plenty of info out there from people that have done a SAS, and what they do.
