I have a pair of 4.111 diffs pulled from my truck. They are in good condition, with no chipped teeth or other problems. They may require cleaning and re-adjusting. $200/ea. or $375 for the pair. Selling because I have a newer set of rebuilt diffs to install in their place. I also have a 3.70 diff (out of a 1981 BJ60 front axle) for $100.
