this is an excellent condition 14 bolt sf rear end that i had machined to 6 lug added disk brakes 4.56 gears and a detroit locker to. the detroit is less than 2 months old and has only been used for one day of wheelin. i also have two spare shafts for it. i am asking 600.00 for it, but i am negotiable. i live in wyoming but make frequent trips to denver.
