Welcome,
Excited to see the build! Quite a few of us have done SAS on the H3. my personal one has been done twice, once via THORparts using a gm dana 44 and the stock rear end, and a second time by me, using a gm dana 60 and 14b.
As far as steering going, ive seen a few different boxes used. I am using a toyota fj80 steering box THORparts made this decision when it was first being build, laregly due to the forward facing pitman arm. This let him and I slide the front axle forward, right now a total of 2.5". This box also sits outside the frame, better clearance with the motor, longer drag link, etc. Mine came ported for hydro assist from the previous owner of the box, i had it rebuild by redhead steering at one point. FJ80 box also doesn't have a master/indexing spline on the sector shaft, so you can really fine tune the alignment if you want.
You can use a rear facing pitman arm box, its just more packaging and harder to slide the axle forward and get all the clearances you want. squeakyh3 made it work very well.
Some of the ones used:
FJ80 - outside the frame, forward facing pitman arm, no master spline on sector shaft
Nissan xterra - outside the frame, rear facing pitman arm, does have a master spline on sector shaft
Toyota IFS - this is a newer box that thorparts has used - forward facing pitman, cheaper to source
Reconh3 - not sure what he used, a jk or PSC box of some kind
IMO if you're trying to get wild with it, which sounds like you are , choose one that does a forward facing pitman arm, this will let you push the front axle forward to clear 40s, 42s, or whatever you want, with less trimming.
Here are some of the build threads:
Where i started my version 2.0
Not too much of an update. I did remove the dana 44 and the 10b, which have been sold to a good home. The h3 is now on jackstands for awhile while I slowly work on her. Parts have been slowly rolling in. I hope to have her on the ground by the end of summer.

I hope so too. It is an old customer of mine. They are employee owned and good people. I’ll manage people for the first time, pay bump, all good stuff. It will be a challenge I’m sure and at times I may question, why didn’t I just ride it out at where I’m at but I’ve been frustrated for 3 years...

Recon H3 built by offroad evolution in california
Instead of copying my old build thread, I thought that my August 2011 ROTM thread was much more complete. This is by far the most complete compilation I have put together of my build. This is where it all started :) I waited two years for the Alpha to come out. I knew a vehicle with that...

A compilation of SAS rigs, (needs to be updated)
This thread is intended at a historical documentation of SAS builds. This will include H3s and H2s. I will do my best to keep this updated as new builds surface/are discovered. A lot of this was already assembled by @06 H3 . Builds evolve, so the information in there will be whatever is...
