the way that the shackles & hangers are laid out from the factory, a longer shackle will give you a drop. I think a flip would be way more drop than you would want , but you should get approx 2" with a shackle, & you could also take the perches for the front spring eyes off the frame, & move them up to give a little more drop. You need to mark & redrill the frame for the brackets, & be sure to use some hardware to replace those rivets! I did a flip on mine, & tossed all but the top 4 leafs, but it sat the rear too low. my fix was to knock off all 4 spring hangers & move them DOWN on the frame a couple inches , to raise the truck back up a tad. I figure approx 5 1/2" on my rear drop, & I have 2 1/2-2 3/4" clearance tween the rails & the rear diff (no notch). this is not a problem for my useage.....but I dont do any hauling with the old truck. You can get a good idea on a flip drop, just measure the thickness of the spring stack(that 1 ton stack is plenty stought), so Im guessin you will have better luck with shackles & hangers if you need a 3-4 " drop......
