You're probably going to need a longer shackle than stock, with a 3" lift spring. To correct the inverted shackle (don't drive with it like this), take the weight off the springs, and if necessary, use a pry bar to get the shackle facing rearward as you put weight back on.
If the shackle inverts like it is now when you flex the rig, you will damage the shackle, spring and potentially the shackle box. I'd also consider HDOffroad's shackle relocation brackets.
