Instead of all the trouble of lift springs and body lifts, could he get away with axle relocating plates on the leaf spring. I think most plates move the axle 1" forward. Some outfit called 4crawler.com sells them.

Check out Rocky Road Outfitters too if you are looking for ARB/Old Man Emu leaf springs. In the past I noticed that they have pretty reasonable prices. Last time I called there the phone was answered by a real 4x4 nut instead of some corporate cubicle/telephone jockey. -- Matt
