I Found the Magic Button!

So, when we completely disassembled the chassis, I made sure to keep each of the shim packs and associated parts in separately labeled bags. From what you wrote, it would seem that maybe it could be put back together differently, regarding the shims.

After my truck was lowered (ECE) 2.5 up front and 4.0 in back, I took it to a good friend to align. It drove great and I am hesitant to reassemble it differently, yet I know that having it completely apart and reassembling it may mean that it won't be the same. I also feel that it would need to be put back on the alignment machine, but I'm just trying to get it close enough that it could be driven w/o destroying the tires in a short distance.
