I have a full spool for a 14 bolt that I paid $250 for and had brand new timkin bearings and races pressed on for approx another $50. I never used it and its sitting in a hefty bag full of gear oil right now. im not sure what brand it was but it is NICE. I can ship it and its HEAVY. Its super easy to install. You remove the 14 bolt cover and carrier. You bolt your ring gear to it and then put it back in and you are locked stronger than any locker. I need to get $200 out of this since I am already loosing 30% on something I never used. I accept paypal or pickup.
