We also opted to not use the t-case drop kit, since we were running minimal lift, and we had the added rear driveline of the LJ. But we discovered the hard way that on an automatic-equipped LJ with the optional skidplate, the driveshaft doesn't clear the support bar for the front skid. We learned from OK4WD that even a stock LJ with the sway bars disconnected can have this problem. We threw the spacers in to check for clearance and found they were taller than needed. So, we cut them in half and reinstalled. That gave us the clearance we needed, but the first time out wheeling, we hit the skid on the rocks (big surprise). We decided that transmission fluid in the pan was more important than dragging a skidplate so for the time being it is staying.
