Here's a couple of links to body lift installs.
Budget 4 Door Lift
Tracker Body Lift
I used a spacer kit from lowrangeoffroad.com, and when I did mine, the
instructions were something like ...
1. remove grill and then headlights
2. then remove the bumpers, rear has a cover piece to take off first
3. remove the little metal clips that hold the front brake lines to the struts
4. lower the purge canister from its mount, remove center console and shifter
mechanisms
5. release the rubber hose that connects the air cleaner box
6. remove the three nuts on the passenger body mounts, and remove the
one bolt from under the passenger headlight
7. loosen the nuts and bolt from the driver side -but dont remove yet
8. lift passenger side body off of frame using a 2ft long 2x6 to distribute the
stress and prevent warping of the body -be careful to watch for any wires
hoses or other obstructions
9. lift body up ~4 inches and install spacers - there are four through the body mounts and one that gets glued in place between the two center ones
10. lower the body keeping the spacers centered around body mount bolts
and install special nuts (these are countersunk into body spacers)
11. glue the 5th spacer into place under body cushion
12. snug down the nuts / bolts and repeat process for drivers side
13. check the fuel filler hose to see that it does not get stretched - you
may need to add a short extension section, or move the ends up a half
inch on the tank and the filler neck
14. reconnect and then double check all the hoses and air box intake, purge
canister, and brake line clips
15. tighten all nuts and bolts for body mounts
16. replace headlights and front grill
17. using a torch, heat and bend shifters to fit - I bent mine forward about
two inches
18. re-install shifters and center console
I may have missed something
