First of all they won't bolt on. Any front axle from a fullsize Jeep, whether it's a Cherokee or Wagoneer, widetrack or narrow track, will have the spring pads at 31.5" apart. CJ frames and the leaf springs are 27.5" apart. For the front axle you either have to narrow the axle or build mounts outboard of the frame rails for the springs to bolt to.
You can't move the perches on the front axle because one of them is cast into the differential housing.
The rear axle will be somewhat of a bolt in once the spring perches are moved inward to match the width of the CJ springs. Welding is required for this operation.
Google "CJ Wagoneer Dana 44 swap" to see examples of what all is necessary. I've only touched on the high points of this swap.
