this is my delema. I have a 79 toyota pickup. at this moment i have stock springs in the rear with 2" lift blocks and 2" lift shackles. in the front i have 3" rough country springs and 2" lift shackles. My flex is not so good. what would be a better way to get some good flex out of it. Im thinking, but not shure of, moving the rear springs to the front, and puting chevies in the rear. the problem is my frame is choped at the shackle mount so i cant move the shackles back any. i was told that with the cheys you move the shackle back " and the mount forward 11". ovyisly i cant go back any but i could leave the shackle where it is, but angled back and just move my axle forward 3-4". what do you good people think?
