I just read back through your thread, first things I would do, get rid of the block at the rear shackle along with the the tube spacer that you have between the frame and front spring hanger. You will loose a huge amount of lift right there. If you want to run teh hanger that far forward, extend the frame or weld the drop hanger to the front of the frame and gusset the hell out of it, which will drop you down even more. Your front shackle tube lookes to be farther forward that normal, which is good, so when you redo the hanger in the front and change to a 3-4" front spring you will have a good shackle angle. The rear spring hanger looks like it may be a tad forward, but getting rid of the rear shackle block and adjusting the shackle hanger accordingly should net you a decent setup.
