Air cylinders up front on a Trailblazer?

Anyone experienced (i'm not) on how i'd install an air cylinder on the front of my trailblazer? its 4wd/awd, but has a coilover setup, not a differential up front. i've provided 2 pics of it. Just curious where i'd mount the shock, i'm guessing the cylinder would take the place fo the existing strut&spring. thanks-ahttp://filebox.vt.edu/users/acrain/TBsusp/DSC06675.JPGhttp://filebox.vt.edu/users/acrain/TBsusp/DSC06674.JPG
