Going through a ton of totes and patching together all the components needed for my engine compartment. Having accumulated many different parts over 20 plus years and having a rather weak system of identifying what came from where, I was surprised to find that I have 3 power steering pumps and have no idea which one came out of the car 17 years ago. My 60+ year old memory can be faulty at times! Chrysler 300 1967 440 TNT. Two of these have the large indent, one the small indent (Black one) Two of them have caps with the little dip stick. The Bluish one in the center has a plate on it that says "remanufactured to Chrysler Specification, Edelmann Industries, California, Denver" Are any of these correct? All of them are firm, rotate freely and have no slop in the pulley. I was going to freshen one or two of them up, rather do that to the right one, yes? I imagine all of them are non originals, but would welcome opinions!
