First get it so its level when aired out. put some bumpstops in or blocks of wood. Where you planning on bridging your notches or not? If you bridge it you could mount from the bridgedown to below your axle. You can look at www.balisticfabrication.com in there brackets and tabs, or www.speedwaymotors.com look under race parts (rear suspension) they both have parts you could work with. you have alot of travel so you will have to find or make a mount rear end that hangs below the rear(like a coilover mount) I'd think somewhere around 4"-6" and run it up to a bridge and you might want put a shock mount that has multiple holes (like a front 4link mount for drag racing) so you can have some adjustability. That way you get some distance between your shock eye mounts when the truck is on the ground. The more distance between the eyes when the truck is aired out and the shock is compressed and the the more travel you'll get, but you still might have to figure out a way to limit that 23" when fully aired up. Hope these suggestions might help give you some ideas and good luck!
