8 3/4 rearend NEW "Lock Right" brand 'Automatic Positive-locking differential. 1/2 price.

You guys step up if you want it. I appreciate the courtesy. I asked the question thinking it might help Miggy sell it if I was right. A guy on Moparts had suggested a diff like this awhile back as a way to get the traction without a trip to the axle shop.
Good luck, Miguel.
