As Drone said, unless you have a place where you can make fabricate or even just weld it may be a long project. Trail tough does make a kit for trackick's, the price is up there but defiantly worth it.
You will want to rear gear your R&P or be prepared to hate driving on the road.
I'm not sure how crazy you are going to get with this build but the basic layout of part that you will need to complete this build are...
You will have to make a front cross member with 2 spring hangers, 2 rear spring hangers, 4 shackle mounts, 4 shackles. That's the basic do up to get the axles under the rig (with lots of small things left out). Now its time for steering, the stock Toyota front axles use a push pull J-arm steering set up stock. So you will have to buy some vendors high steering kit buuutttt if you want to use a your kicks power steering you will want to get sky mans Toyota to zuki high steer. Now you can turn your kick, time for some breaks.... I'm not sure of the master cylinder size on kicks but on samurai you can just swap Toyota brakes right on over due to them both having 7/8th master cylinders.
Turning the tires is a whole different story, for your R&P you would want to go at least 5.29 if not 5.71. Then you have to adapt your drive shafts to a Toyota flange (not hard just drill it out or get an adapter) With the extra lift your stock drive lines may not be long enough or be able to handle the angle there going to be run at....this is when you have to call up a Drive line company and get one or two made.
That is pretty much a super quick idea of what it will take, with a lot of small stuff left out.
Getting a kit would keep you on coils so it would be a nice smooth ride!
Hope this gives you an idea
