I did my sas and rear axle swap, lift, tires, suspension, drive shafts, steering, for under 2 grand.
Step it up a little each time. Maybe coil spacers or the washer trick and a shackle for the rear for starters.
60 bucks total if you buy them. Under 20 if you make them.
A lot of people bitch about body lifts but they're a great additional lift. I wheeled with 33s and a 3" bl for a while and had no problems. Allowed for bigger tires to take me places I never thought I could go. BLs also give great room for sliders, doublers, secondary gas tanks, and running your exhaust higher up.
