Handling upgrades for leaf spring rear?

[2ndroundko]

Long time no update. I got the control arm bushings in and the sway bar, but I left the back stock other than the bushings. That in itself made a considerable difference. As of now the truck is blown apart for bodywork. While the bed is off I'm going to flip the shackle mount and take out a couple leafs. while Im addressing the back I am also going to add some bracing to the frame in an A-shape to stiffen the frame a bit.
