Geo tracker swap, get a pump mount and a steering box mount and a junkyard tracker power steering system and it's pretty straightforward. You can get the mounts from most any samurai parts slingers. I actually have both mounts for my daughter's sammi that you are welcome to copy if you were so inclined.
I ran the Petroworks wedge steering box mounting bracket. It is more expensive than some of the others, but aligns the box correctly with the steering shaft.
What size tires and is the front locked? Tracker swap is cheap and easy and works well for smaller tires. Big tires and lockers you'll probably want to go IFS toyota box.
It's locked and I don't plan on going bigger than a 31 right now with the hub's unlocked and in 2wd I can't barely turn the wheel moving or sitting still and it only has 235's right now don't know if the box is shoot or what
On zuk axles the tracker stuff will point anything the axles will withstand. I have a buddy (maybe he will chime in @junkyardog) that runs yota axles on 33s with tracker stuff and added a hydro assist and it worked good. I would add a decent cooler for fluid capacity. The brackets i have are very similar to the ones @drkelly posted.
My front was locked with 34" LTB's. The Kick/Track power steering stuff worked fine for normal trail riding, but I could have used more power for technical stuff. It was WAY better than the original manual steering.
