I'll look into it, but it sounds like the same thing we all do to lift our trucks. Torsion bar crank in the front will net 3 inches without much trouble, and a cheap add-a-leaf and shackle upgrade will get the same in the rear without trouble. Any idea how much this guy paid to have it done? Even all new parts for the rear would run less than $300, including poly bushings, shackles, leafs, new center pins and U bolts. The front would just need an alignment when it was done.
Only thing I found right off looking around was
http://www.central4wd.com but they just list body lifts for the luv on their website. I'll dig through the yellow pages later and see if I come up with something.
