Hi Steve,
Welcome to LOST!
Some good names in KJ lifts are OME (old man emu), JBA (Jeepin By Al), and Frankenlift. Read lots and lots of posts and stay away from spacer lifts. That and pretty much treat Tommudd's advice as gospel. He has lifted (personally in his own driveway) more than 60 KJ/KK's and owns 2 lifted KJ's, so he knows his stuff.
Enjoy and feel free to ask questions. Good to do a lift right and save $$$ and frustration.
