IIRC, 33" tire should clear with minor front bumper end cap trimming and a small crank of the torsion bars. Of course, it really depends on the tire width and wheel rim/offset, but if they are not unusual you should be okay. If you can find a set of stock GenII rear springs you can gain a modest and inexpensive lift in the rear. OME also offers rear springs. In addition to the considerable expertise found on ExPo, take a look at 4x4wire.com for tech issues too.
