XJ axle swap/build

Well I donít really know where to start, but Iíve had my XJ since I was 17 and I have been tinkering on it on and off since then ( Iím almost 31 now). Being in high school and college I didnít have the money, time or place to do what I really want to it, but Iíve been able to do small things over the years. Now that Iím done with school and have a little bit more time and money I decided to send it and do an axle swap so that I can run 37ís comfortably with having to worry too much about breaking/bending axles etc.
So far this is what I have:
- 1990 2 door xj with ax-15 and 4.0, moon roof and wind wings
- RE 4.5 inch short arm lift full spring pack and 3/4 inch spacer to level front/back
- RE track bar and sway bar disconnects
- XJ Dana 44 with ZJ disc brake swap and factory LSD
- 94 HP non-disconnect Dana 30
- pro comp series 51 steel rims
- 33x12.5r15 Mastercraft MT tires
- RE monotube shocks
- RE extended brake lines
- OE XJ rear tire carrier
- WJ MC and booster with ZJ prop valve
- carpet remover and bed lined interior
- 50 led light bar (I know, ďlockers before light barsĒ)

What the plan is:
- disc brake swapped sterling 10.25
- trussed HP Dana 44 from 78 F250
- 3 link front from stinkyfab with tcase skid
- high-steer from ruff stuff
- front and mid frame stiffeners
- Durango steering box
- ruff stuff track bar
- 37x12.5r17 Cooper STT pro
- method 701(?) 17x8.5 with 4.75 bs
- rock sliders and bumpers with cut/fold
- winch
- rear elocker swap from 2011+ sterling 10.5

What I have so far:
- both axles with 4.56 gears (in process) and Torq locker for d44 and TNT truss. U bolt eliminator brackets for 10.25. Warn Premium hubs for d44.
- ruff stuff parking brake calipers with brackets and rotors for sterling 10.25
- frame stiffeners
- stinkyfab frame side link mounts and tcase skid
- enduro joints from bars 4x4
- Track bar/mounts and part of steering from ruff stuff (need to get tie rod and another high steer arm)
- diff covers from ruff stuff
- new seals, ball joints and bearings for both axles.
- Durango steering box

Where I am at right now:
- axles are torn down and in process of being re-geared.
- working on getting Jeep ready to install stiffeners while axles are being geared.
- accumulating parts needed for swap, which is just a few steering parts I think.

I might be a bit in over my head, but so far my wife has not stopped me, so Iím going for it while I can haha!
I donít have a lot of photos of my Jeep as when I take it out, I usually forget to take any photos. Iíll try to attach some if I can figure it out.
