72 Chevy Lift?

[Rockit]

A buddy of mine is looking for springs for his 72 K10 bobtail project. Since I've never been a big chevy guy I don't know where to point him. Any sugestions for some flexy leafs that will provide around 6"s of lift? :dunno:

Thanks!

I don't know of any specific brands that make a kit. But what I know is that national spring has a very good selection. Not too sure about quality.
