I'm running Marlin 5" all the way around as well. I setup the rear shackle mounts like that so I wouldn't need more spring or shackle to level the rear. I'm also running 4.5" shackles in the front and 6" in the back. As far as the hangers for the leaf, I would go back about an inch from the measurement CJ gave me, at 28" back, it placed the tire forward in the wheel well.
