Are you talking about the ford 1-ton hangers and springs? If so, I am doing the same thing as you, but, like a dumbass, I went to the dealer and bought front and rear hangers for each side of the truck, no returns. I was going to cut out the bottom of the rear hanger and do the flip on the cheap, then I realized I shoulda bought another set of front hangers for the rear. Like I said, DUMBASS!! So now I am stuck with these useless rear hanger/shackle brackets. I just went ahead and bought some ORD 1-ton flip brackets, because the ford rear ones weren't tall enough to give me the lift I was looking for after the flip. Hopefully some ford dude wil need these one day, and I might be able to recoup some of the cash I wasted.
