You may end up running a little high in the rear with both the AAL and the shackles. This is the setup I'm running, however, I've got the control arms in the front allowing me to turn my torsion bars MUCH further than you can go with stock.

You may want to put on the AAL's with the stock shackles until you get some control arms. You can add the shackles at that time since your front end will be able to go higher. Torsion bars will only stiffen the front end, not make it any higher than you can go now, that's the job of the upper control arms.

Yes, you get a new leaf pack bolt, and yes you toss the load leveler. Make sure you measure the AAL's and your springs from center pin to the center of the spring "eye". One side of the springs are longer, make sure you put the longer side of the AAL's to match. Pick up some black Rustoleum spray paint as they come unfinished.
