Steering box needs compatable pump

[lenguini]

I have a pre 1980 steering box and want to find a pump thats compatable with it in the Type 11 style.

There are a number of these pumps that look exactly the same,but being that its for my 65 on a sb 400hp,Im confused with high flow,low flow and most of all,a part number!

I need to confirm fitting sizes at both ends so I dont order this twice...and any suggestions on a braided hose kit as well.

I'd appreciate some input from those who know for sure.

I posted a couple pic's here of the pump I want to use.........possibly running this type resevoir if I have the room under the alternator.
