joe jeep. I am doing this mode as we speak over the holidays. I have basically a rubicon setup in my 99 TJ.I have a 4" lift. I would be happy to share my recent experience.

I have installed the 241OR rubicon 4 to 1 transfer case. I have a D 44 rear axle. The skid I chose was an Nth degree 1.25 Tummy Tucker.

#1)Raise the body 1", dont bother with the tcase linkage as you will be moving it again for the belly up.
#2) install the tcase( you dont need to)
#3) install the belly up skid, I gained 4" clearance
#4) install adjustable upper controll arms so you can point the axle pinion
#5) I had to notch the back of my spring perches to allow the shock rods to clear as rotating the axle creates a problem, there are product to move these as well.
#6)measure for the double cardin driveshaft, make sure they know about the rubicon yokes. I changed mine to u-bolt style both ends
My ujoint centers measured 17 1/8"
I did not do the motor mount lifts as my driveline angles are 19 1/2 deg
which is acceptable, the 1" mm lift would give me back another 1.5 deg
