Is the ARB klift the Old Man Emu kit, torsion bars and leaf springs?
From ARB's PDF
If it were me, I would start with modifying the pinch weld body seam along the firewall(beat it flat or cut it off), then beat back the lower corner to the body mount. Might need a little cutting of the lower fender.
If that doesn't clear the tires, you can go with a 2" body lift. This will require modifying the cut-out in the floor for the shifters(if you have a 5-spd), lowering the radiator, lifting the front bumper, etc.
Or, for a little more money, 1.5" ball joint spacers and 3" longer shackles(yields 1.5" lift). This lift will require a small modification to the upper A-arm, new ball-joints, and an alignment.
With a combo of the 3, I am able to clear 35x12.50's on 15x10's w/2.5" backspaced rims. For 33's it usually takes two of the mods.
Other options,
Crank up the torsion bars and 3" longer shackles. Will need an alignment afterwards.
Different backspaced rims.
4Crawler Off-road has the body lift and ball joint spacers, both are quality products at decent prices.
