"Lifting" a 2wd 68 C20

[YaoGuaiChevy]

Hey all, I have a 1968 Chevy C20. It sits at "stock" height and I wanted to raise it in sense to make it look cooler. My girlfriends dad said he had the same truck and put Air Shocks on all sides to lift it up and make it look more like a 4x4. I'm not mudding with mine or anything of the sort I just like High trucks. My concern is that I have Trailing arms instead of a leaf spring set-up and I was wondering if that would affect the "lift" of the Air Shocks? These Shocks are the kind where you can air them up with a garage compressor if that gives any more info.

Please don't just say "Better off with a 4x4" I don't care about your opinion.
