Im in the process now of getting the hangers ready. I am going w/ the front hangers of a PU moved to the back. What my question is, when placing the new hangers, should I move the bolt of the hanger forward at all. I am only going for 2 inches instead of the tradional 4. I am just trying to avoid the shackle kicking over, and I dont really want to/ have time to play trial and error when there are so many here that have done it. So should I keep the hanger bolt centerline where it is or move it forward?
