Way back when there were no kits to do a shackle reversal I just used the front rear spring hanger and support and mounted it in the rear with grade 8 bolts. The hardware cost more than the mounts. I got the 4 inches of lift for about $25.
For the front I would get some EZ ride springs from SD spring they are the cheapest around and work better than the ranchos I used to run that are NLA
