Can some of you give me some advice or opinions on what kind of rear axle and gears to go with, as mine is shot. I am not at all familiar with driveline problems. I run 4" inch lift springs in front blocks in back. My 88 has the 350. I do not do hard off-roading mainly mudtrails and on road. I looked up several posts where people suggested 12 bolt but would you change out gears? i have been running stock up until now.
