I have an 84 K10 with dual 10bolts, 3:42 gears. I want to have a posi or locker in the rear, but which is better? I dont offroad much, and it HAS TO BE 3:42 for a 8.4/5/6 10 bolt truck rear end, preferably cheap not expensive. So basically, what should IO get? Posi or Locker? Anyone have any good links to parts or info? All help appreciated.
