Whats the difference in leaf spring rears on 67-72 trucks versus 73-up trucks? I see rear axle flip kits for the 73 trucks,but none for 72 trucks.Does anybody have a pictre of a 72 truck with just the extended shackles that lower about 2"? What if you use the shackles and take one leaf out of the springs,how much difference would that make? Thanks
