You should clear 31" with the AAL and shackles. You only add one leaf per pack, using the two 2 leaves from 2 front spring packs as donors.
You don't need a torch, I used a cutoff wheel on an angle grinder to open the tops of my spring clamps. You can use heat and bend them open and closed, but I went the easy route. 4 new spring center pins and that's about it, easy to do with the main leaf never coming off the jeep.
