For a 35" tire i would go with Toyota power steering, the trakick power steering is a little bit small for that size.
I mounted up a Toyota IFS power steering box and pump, if you have any way of welding/minor fabricating its not very difficult to do.
Here is the IFS box mounted
Stock pump before cutting into it.
Motor side of the mount.
Altered pump bracket.
Pump installed with trail toughs double V pulley.
Top view, used a car quest belt (part# 7330)
Added a big ass power steering cooler too.
So far it has all be working great for me, no problem turning my 34 LTB's at idle. While at a stand still in the rocks you do have to give it some low revs to turn it with out killing the engine...but thats with a stock 1.3L
Not sure if this is the rout you are willing to take, just tossing around some ideas .
