To the original poster - this is called a "b*stard pack". Generally speaking, most people recommend buying complete sets of leaf springs from companies like OME, BDS, or Zone. Some people do make up their own leaf spring packs, but I'd recommend that you look around the forum and research on lift springs, lift kits, b*stard packs, etc.
For your original question, cutting the bolt to remove the shackle is perfectly acceptable, and what I would do. It's much easier than dropping the tank.
