By 'diff', I'm assuming you are talking about the entire FJ-80 front axle. There are some creative home-brew steering ideas that work well, albeit some work better than others. Fireball on here has an 80 axle under his runner. There's a few threads on Pirate describing the leaf-conversion. OTT in Canada makes a crossover steering for the 80, but it's really expensive.
What exactly did you have in mind for your swap? Give us an idea on tire size, desired capability/streetability, and other build ideas.
I checked out your pictures... Those rims look sweet. I have always liked the black steelies, but wasn't fond of the 'trapezoid' wagon-wheel cutouts. Where'd you get those? How much?
