I have swapped an '89 4Runner body onto a '94 pickup frame. Just use the front body mounts for alignment and cut all the 6 rear mounts off the 4Runner and bolt them in place to weld them on. You will also need the 4Runner gas tank and brackets or a mild body lift to clear the pickup tank...
It's really no big deal if you can cut and weld.
You will need aproximately 2 large pizzas and one case of beer to get the cab moved.
