Right now I have the tuff country 4" springs front and rear on my 79. As you all know they squat with the top on, the rear seat in there and a tank full of gas. I also have a heavy sub box in the rear. My question is since I have 4" rear springs. Would the ORD 2.5 inch shackle flip be too much? Or does the 1" add-a-leaf be plenty? I already have a new driveshaft thanks to Jesse. I also thought the 2.5 shackle flip would help out on pinion angle a bit since I could use a little bit more. But I don't want it to stick its but up in the air.
