Tuff Stuff

Hello everyone well I got a 67 dart with 360 and I just got the borgeson power steering.
So I need a power steering pump for it and I was looking into tuff stuff does anyone know which one is a good one for it theres a lot on the website but I don't know which saginaw one would fit specifically? has anyone used tuff stuff pumps and which ones? the reason I chose tuff stuff is because I don't want to worry about leaks or anything major for a long time. thank you
