Power steering pump for 67 Charger Hemi needed? Where to buy?

[dgp_naples]

I am looking to buy the correct power steering pump for my 67 Charger Hemi. My parts catalog shows two types of pumps used on the Chargers:

Plain End Oil Pump Shaft w 4-5/8" I.D. Oil Pump Resovoir Part # 2585 532  (Does not state the manufacturer)

or

Key Slotted Oil Pump Shaft w/Nut (Saginaw) Part # 2537 664


The one I found at Classic Industries does not fit the 67 Charger according to their drop down list of cars/engines.

Any direction would be very helpful. Thank you.
