Why don't you go with this kit from 4WD Hardware?
4WD kit is a BDS
These leaf springs are BDS, and the kit comes with shocks, xfer case lowering kit, new U-bolts and drop pitman. Of course it comes with all new bushings and boots too. All you need to add to this is extended brake lines and maybe a new steering stabliizer. That's what I added to mine. They make this kit for CJ's with or without power steering. If the link didn't come out right to to 4WD.com and look up part number 493240
2004 Rubicon, 6" lift, 35s, winch, hard top, full doors, bumpers, tire carrier and rock sliders.
