Difference in power steering pumps?

I believe 1967 at least used a Federal pump (that is what was on my 1967 Barracuda). The TRW pump is the same thing. Saginaw takes different brackets and a different pulley (I know this because I installed a Saginaw pump as a replacement). About the listings, Mopar kind of screwed-up the replacement parts market sometime in the late 70s. They superseded a bunch of part numbers and failed to cross reference them correctly. So there are many parts, especially brake parts, for 67 and to some extent 68, that are not correctly listed, even though the part is still being manufactured for other applications. A little detective work is often required.
