Therefore another question. I'm pretty sure that the Chevy bolt 10-bolt center hole is slightly smaller than the BOP center hole and therefore the BOP backing plate bolts on to the Chevy, but the smaller Chevy 10-bolt backing plate won't flush up to the BOP axle housing. So is the 12-bolt center hole a little larger and the same as the BOP?
