Parts list as follows: calipers, pads, rotors, backing plate/caliper bracket, parking brake shoes and hardware, studs and nuts from donor axle to mate bracket to housing, longer lug nut studs (if using aluminum wheels), soft brake lines and ZJ prop valve (optional as far as i'm concerned).
I rebent, shortened and reflared my hard lines as they will be too long with the disc setup, you could also get creative looping/bending them to take up the extra length. Be careful though, don't want to kink them. You'll also have to figure out a way to mount the inside end of the soft line to the axle. I drilled a hole in the axle housing, tapped it and bolted the free end of the soft line down. I've seen other guys weld it on, i didn't have access to a welder at the time. If you do this, seal it up with some RTV.
