A guy I know is selling Dana 60 front and rear axles built up and ready to go with transfer case, 4.56 gears and lockers front and rear. They have drum brakes all the way around and leaf springs in the back. Ge wants 1500 bucks for the whole setup, but could prob be talked down some. How much work and extra money and work would it be to put these on my TJ, do you recomend it, and is that a decent price???
