86 C-20 Static drop and other parts, where to find?

I'm thinking about picking up a C-20 crew cab that I found, single wheel, not dually, and just wanna know where I can find some parts for it. I just want to static drop it to hell and use it as pretty much a beater/work truck. Do they make a drop spindle for that truck, or is it any different from the C-10. Where can I find springs and whatnot for the truck also? What about big brake upgrades for it?
