please dont kill me, looking for rear leaf shackles

Those Dakota shackles won't work. You need basically 2 pieces of flat bar with holes in them. One thing I don't like about shackles is they change the pinion angle to the driveshaft. Anytime you raise or lower just one end of a spring you affect the pinion angle. IMO a better option is helper springs that go around the shocks. They won't affect the pinion angle
