You will need to relocate your upper and lower spring perches first. Get them set so the spring is straight up and down. You cannot outboard the shocks unless you have the final shock you want to run in hand. As you will need the shock in hand to set the towers, and lower mount, you will cycle the axle many times while outboarding. You will disconnect the sway bar, trac bar, you will need to know coil bind and full extended length of your springs, you will cycle the axle with the tires off, tires on, one tire off one tire on(full compression on one side with tire at full stuff, and tthe other side at full droop) than switch sides. You will be looking at things like, does the rear diff cover hit the gas tank, does the trac bar mount hit the tub, where does the tire make contact with the body, how much metal needs to be trimmed. Make sure the axle is centered prior to starting, watch for driveshaft binding at full droop, as you may need to add a limit strap. This is a very short version of what you will be looking for when outboarding. Do a ton of research. This is a project that takes us novices 24-36 hours of actual labor to complete. When I did mine it was a 16 hour saturday, a 12 hour sunday, plus a few hours each night after work to complete. Most people who outboard go to a 12" travel tunable shock such as a fox 2.0. as it is a lot of work and you will only want to do it once.
