8 3/4

If the guy knows Mopars, you will NOT get that rearend for $100.00. However, you should still buy it and trade it here for an 8 1/4", which would have the LBP you need, and still be plenty strong. I would go as far as saying that you may get an 8 1/4" SG equipped unit in even trade for an 8 3/4" open rear, if all of the components are included in the deal!! Geof
