rockers on the ground ???

change of plans.. instead of building a motorless air hopper.. im going to body drop it and bag it.. i got a crate motor donated to me from a friend with a shop.. i gotta put thier shop sticker on the truck.. but hey.. free motor plus tranny.. anyways i need to know what goes into doing a body drop.. should i stock floor it.. or what?.. and how much will it take to lay full rocker panels on the pavement??
