Early classic enterprises makes kits for our trucks, that's what ill be using, although you'll have to upgrade to front discs if you use their spindles. Drop spindles move your arm up however much to actually move your wheel up (lowering your truck over the wheel). Drop coils just drop the suspension however much they are rated for, so 2.5 drop spindles and 2 inch drop springs would lower the truck 4.5 in total. For the rear use blocks and springs to move your rear axle up (again drops the truck around your wheels). Please correct if I'm wrong however
