A long bed s10 seems to be the donor frame of choice for most of the Deco and AD trucks i've seen.. there's a dude that makes a "kit" to slap an AD body on them.. AD Engineering is what his outfit is called.
Looks like just a bunch of riser deals that bolt or weld to the frame and match up with the holes on the body. Once you get your body to a place you can measure the mounting holes, seems like it wouldn't be hard to fab those "riser" pieces yourself.
