like he said, the front is direct bolt on. the isuzu and yota use the same bearings. you hav to use the isuzu rear seal if i remember right and you must shim the caliper 1/8 of an inch to center the rotor in it.
the rear you will have to make mounts for whatever rear suspension you have and you will need the rear section of the yota driveshaft to adapt to yours. just be sure you have room for link bars etc. between the wheels and the frame as the yota rearend is about 2 inches or so narrower on each side.
