    Find an 8.5 out of your same vintage LeSabre that has a small block. It’s a direct bolt in, and aftermarket gears are plentiful

    Some 71-76 BOP C body cars will have your current 9.3 rear but none will have a 4.11. 3.42 is about as high as they came and they are rare. There are no aftermarket gear sets for the BOP 9.3.
