To get a full 2" lift, you would need shackles 4" longer than original. I don't recall if the shackles are on the front or rear of the leaf springs, if on the front, it may make it real squirrelly driving it down the road! If at the back, it may make it a bit harder to turn. If going that route, I would lengthen both the stationary end and the shackle.
