Need Help with Power Steering Pump Bracket ID

Upgraded by my 67 barracuda to the 73-76 disk brake suspension.

This pump was included with the k frame and had these brackets on it. I know it's a Saginaw pump ( I believe a later style pump). Can some tell me if those are small block brackets on the pump? If so, does anyone have pics of how it mounts on the car?

Additionally, should my crank pulley be the same for both the alternator and power steering pump pulley? I've see them with equal size pulleys or ones with a bigger power steering pump pulley.
