Power Steering Questions

Thanks Andy, I am definitely interested in the brackets. Your the resident big block expert... is there a differencein the big-block and small block pumps? I was looking at the chrome unit on Rockauto with shows up for a '74 Small block Duster, but not a '70 440 roadrunner, so I am thinking there is? I don't always trust the parts look-ups, especially when our cars are so far from factory. I looked at the Borgeson box, but that is going to depend on what everything else runs me whether its in the cards or not.
