Freddie will correct me if I am wrong, but I think your options for a correct GM set of gears for a 12 bolt are going to be 3.73, 4.10, 4.56 and 4.88.
Aftermarket makes 4.30 and 4.33 gears. While they were available from the factory in Pontiacs in the late 60s, I think the BOP rear was different from the Chevy 12 bolt.
