The poly head has an impeller shaft that has a, "D" shape at the motor end.
I broke that poly head and bought a bronze head. It has a screw end for the shaft that holds the impeller. When the bronze head arrived, it did not have the shaft.
I am in communication with the company and I hope they make it right for me. They now, because of my issue have listed the bronze head with the correct shaft.
