lowering c20, the easy way?

[c20pickup]

im looking to lower the rear of my 70 c20, and maybe a 1 or 2 inch drop up front. in the near future i will be changing spindles to 1971 disc brake spindles, so the coils in front have to come out, i read somewhere that cutting one coil is equal to a 1 or 2 inch drop, first of all, is simply cutting the coils a safe option to lower, or should i just buy drop spindles? id rather not buy new spindles, because i have a set of disc spindles here already? how much of the coil should i cut for say a 1-2 inch drop up front? and in the rear, being a c20 it sits really high. the rear has trailing arms and coils currently the truck has an eaton ho52 rear end that i plan to swap for an aam1150 in the future, i was looking at just buying blocks for the rear to lowering it about 2 inches. i like the idea of the blocks because then i dont affect the rear springs, and i can kep the towing capacity of a c20. opinions? suggestions?
