Do you want to make it sit level? You can make it sit level by removing a leaf from the spring pack in the rear - must do it on each side. Remove one from the middle. It will only cost your time.
There is no cheap way to properly an older I beam Ranger. Cut your spring will give a hard ride. I installed DJM dream beam on my Ranger in the Front, and used a relocation bracket to lowwer the rear. It wasn't cheap.
Stay alway from rear flip kits, unless you wanna go super low.
