I used the stock chevy shackle bolted to the stock toyota hanger then welded up to the frame. From there I used a 5.5 inch schackle down to the spring (so technically its not a dual shackle since they both dont move but I used two shackles to locate the point of rotation). Worked out great. I think I have between 3-4 inches of lift, its just a little lower than my ruf's which is how I like it to get a little weight transfer to the rear where there is none.
