WANTED 68 Polara TRW Power steering pump

[GMPolara]

I am looking for a working TRW power steering pump around this vintage. I've attached a picture of what I'm looking for. I have the mounting brackets and pulley. Just need the pump.

What does the end of the shaft look like?
Doe it have a smooth end
A Slot end
Or a hex end?

This will change the diameter of the pulley and the diameter of the can that covers it all. Possibly a different shaft diameter, But I'm not sure on that.

All set. Thx all.
