Need help. Finally rebuilding the suspension on my c20

[Mmorgan32]

So I desperately need to rebuild the front suspension on my 70 c20. While do the is I plan on hitting up a salvage yard for a disc brake set up off a 71-72 8 lug. I want to lower it a little nothing crazy I just hate how it looks like a 4x4. What I need is upper and lower ball joints, front springs ( I want a drop spring) and tie rods. And I am considering doing an axel flip. Questions. Where can I find a rebuild kit? Do they make them or do I need to piece it together? I do not weld so what is involved in an axel flip?
