Power steering swap from small to big block

[moparmaniac10]

Here is my dilemma. I have a power steering pump off of my small block 318 and I want to use it on my 440. Am I able to just buy the big block brackets and use the same pump or do I have to buy everything new?

I believe it is the same pump, did this swap many years ago and only needed big block brackets to bolt pump to engine.

which type of pump ?
Saginaw will be the easiest to get the brackets for the TRW OR Federal will be tougher
