I have a set of factory stamped and dated (10/29/70) 3.91 gears and Sure Grip differential..
The gears are in great shape and no chips or damage.
The posi unit has a part of a broken axle still stuck in it and I don't have the tools to get it out..Other wise it is in good working condition.
Came out a 489 case gears are 10 spline
Gears only...$200 shipped

Both together $425 or best offer
Im not sure what they are worth I hope im not over priced
