From what I understand, the 1" and 2" body lift kits are the same (minus the difference in puck size), the 3" kits have a little more pieces involved. On my 2" kit, everything I needed was in the kit, pucks, nuts, bolts, washers, etc. As far as the lengthening the auto shift column (weld in piece), I didn't want to cut and weld in the new piece, so I completely made a new, longer piece all together. Other than that, was happy, no problems with the kits. Only problem you will run into is possible rusty/seized body mount bolts, and you will have to drill 3 holes in the cargo area to hold the lift pucks, chevy didn't use bolts to mount those cushions, just sandwiched them in. Muddysub can atest to this, he didn't drill holes in his, just put the pucks in, ended up losing the pucks when you flex. Hope this helps.
I do have some pics on my webshots if you wanna look. If you want more pics just lemme know and I can take some more /forums/images/graemlins/grin.gif
