The XJ leaf springs won't work, you're pretty much stuck with the MJ springs and you can either run them straight stock or make a bastard pack out of them. When I did my SOA, I just use my stock springs. Mine were sagging a little so when I swapped the 8.25 and doing a SOA only netted me 4.5" over stock. A brand new spring will net about 5.5" going SOA. Since you're swapping axles...old axle centerline to bottom of leaf perch + new axle centerline to top of leaf perch will be your lift.
