Is your block drilled and tapped (above the smog pump) for the power steering bracket? If not you can NOT
use that pump unless you drill and tap your block or somehow figure out a way to get the pump mounted. This thread
has pictures that show the holes in the block and also show what TJ did to make the FJ40/FJ60 pump work.
Check out this kit from JT Outfitters
and that should give you a good idea of the primary pieces you need. They don't include the steering box in their kit, so you'd have to find that elsewhere.
You can buy components of their kit
to help piece together a kit that will work for you.
I don't think what you posted above is what you'll need, but I may be misunderstanding...
