11 3/4 rotors

A17 bearing fits the spindle (1 3/8") but the rotor race is bigger. When I ordered the rotors, I asked for mid 70's full size dodge 11 3/4" rotors......did I miss?? These rotors are 11 3/4" dia.....Is there more then one mopar 11 3/4" rotor???? The inner bearing bore needs to be 1.375 and the race o.d. needs to be 2.48 , any part number for this size?
