You can add hydro brake booster and upgrade the back brakes to 11x 2 3/4 brakes like on many 73 up truck 73 87 square body trucks are a good donor for these

I am planing on 2.5 drop spindle 3 inch seems to much a 3 or 4 inch rear drop spring
Using new rotors and larger rear brakes from a G20 that i picked up which also has the same hd brakes as a 79 C10 and using a hyro boost from a express van
I have a front C20 sway bar I do have a couple of rear sway bars from camaro and a tahoe not sure if i will use them
as for bigger brakes I know the van stops better then my C10 did originally So i will leave it there I can change that latter

Some big brake packages you can re use your spindles by removing the caliper brackets off them
