The info is as simple as this.
Wj kuckles, calipers, rotors (redrill rotors to 5x4.5..simple & can be done in your garage with a decent hand drill)
00-06 Xj, TJ or Lj hubs
Wj lower ball joints (different taper than Xj, tj, zj ect)
1/4" hub spacer
At that point you can bolt on the knuckles with their HUGE brakes & you can still bolt up your stock steering, or whatever steering your currently running. I did exactly this, wj swap with v8 zj steering. Basically do the swap, recoupe some cash then do steering.
To do OTK you will need the JKS wj swap steering, or 1.5" .250 wall DOM tubing. You can either tap the tubing straight out (machine shop) to fit the stock WJ TRE's or buy the inserts & weld them in. If you run a front sway bar you will need JKS raised sway bar end links as well. Some do the OTA (over the axle) track bar bracket but I've seen many many setups not do this without an issue..its mainly to get the track bar & drag link on the same angle to avoid bumpsteering. But with true crossover like this, there really isn't any bumpsteer so its not as important.
A local on 35's & 4.5-5" has the swap, with cross & a IRO track bar in the stock location..angles are the same & his jeep drives like a damn dream, no bumpsteer, no wandering or slope. The crossover is very very nice!
If your interested I've got knuckles, calipers, & 00-06 hubs brand new I can sell ya. You will need a 1/4" JKS hub spacer (40), brake pads & rotors (150), Wj lower ball joints (50). I pulled my setup because I went back to OEM rims which are 15's and 5.5" of backspacing. They do not clear the huge calipers obviously. Calipers are practically new, hubs are brand new. Pm if interested.
Sorry to highjack Scott!
