I'll give you another piece of advice.. on the back brace.. once you figure out the length.. weld the brace all the way to the ends(right behind the bearing brackets).. put the bearing brackets on last... all the other stuff that goes on cut it around the back brace.. that way the axle tubes are way stronger..guys that stop at the springs(leaf springs) so they dont have to work around the bolts.. the ends(past the brace still bend)
