I'm sure this has been asked several time . But i will ask again. I have 87 w/ stock axles on 33's, axle truss's. 6.4 :1 t-case gears. i dont want to put in trac/kick 3rd members(or should i ?). i plan on upgrading the axle shafts with the calmini shafts. and putting lockers front and rear(lock right) so what do you think on gears 4.57 or 5.38 it will be driven on rd. Thanks in Avance.....
