Haha yeah I made it look easy because I did it twice. The first go around was with my ratty C10, then ended up pulling that truck apart and transferring my work to this '72 C20. Things usually come out nicer the second time.
As for springs, I bought a set at rock auto from an old thread I found on here. My truck was a factory big block truck but the front end still came down a good bit with the stock springs. I replaced them with Moog #6454 about $80 from rock auto.
The truck sits great and rides really well, almost level but slightly nose down which is where I wanted it. Below is an updated pic with it sitting right (keep in mind the truck has a 1' body lift to clear the drivetrain).
