Raising the rear

so you are trying to lift the rear enough..so your tires can actually run beyond the flat lip on your quarters?? with the rims sitting out further than they are now?

you can gain some height with welding blocks to the rear subframe, and then running your shackles through them instead of the original location...this will add some ht.
SS springs will also lift it over the saggy and/or oem position. i run SS springs and welded on my own blocks and it works great. but it appears you want another 1-2 inches over my racing setup even..

now for the opinion portion, and please take with a grain of salt: if you actually offset the wheels like i think you are trying, its going to look pretty stupid (IMO), on top of the fact that you will crush your quarters if the shocks ever collapse/blowout/ or you hit a large bump..
