It's ZooKeeper & when you click on the link below it'll take you to my old screen name's webshots page. But I did mine w/a S10 frame & from what I have seen the coil over set up eats up wayyyyyy too much room in the rear then a leaf spring set up. I raised my floor up in the rear about 3 inches because I had a stainless steel box made for a trunk to be hidden under the floor...Joe
