Need some help/ideas with TRASHED leaf springs

[country_boy_112688]

OK so here is the problem, i have recently bought a 1976 1/2 ton SWB fleet side. And today i decided to remove the whole body of the truck and start building it from the rubbers up. So i have the body of the truck off now and im starting to look the truck over and inspect the damage the previous owners may have done, and to me it all seems quite solid except for the leaf springs, that have broken leafs and a s shape to the longest leaf. O and the springs are a 44 inch, 7 leaf pack. And the way i measured them was from the center of each eyelet to the center bolt following the radius of the spring. correct me if im wrong.

But now the question im wanting to lower the truck but i have no clue about lowering a truck, just lifting one. Now im not looking for super low just something that looks good and that can still drive over the hills of Missouri. so i need some ideas on how a drop is done properly and maybe some distributors that make kits, and what to look for while doing a drop.

Thanks guys and gals any info will be appreciated.
