This is a really important subject ; Napa today gives you a 440 pump that “fits”413 but is often wrong . Some early pump block housings had steel plates inside to control flows or take up space behind impeller ? Minor things like temp sensors or bolt tappings , one can deal with but I believe there are at least two pumps and two housings if not 4 in the early B blocks and they have differing pump impeller depth spec . The plate or not is a variant too . Or maybe that fixes a too deep housing used elsewhere. Several wrong combinations fit ok but car will overheat . I have never been a guy with all the part numbers in a book , — but if anyone really knows what the main variations of housing and pump are physically we can at least match correctly . On the other hand getting some of the early pumps can be frustrating — you get 440 pumps . . So if the original 413 pump fails get it rebuilt or get a kit , lacking solid info on crossing over — not hearsay. I think the AC / HD pumps had differing vanes too, from memory , —and while this may be wrong , I think oddly the ac or HD pump has fewer vanes which really confused me — seems backwards . Add that variation to set in depth and the plate or not , a lot of ways to go wrong . Today I would tend to purchase an aftermarket or Mopar performance pump and housing in aluminum that go together , unless your old one is obviously correct / original and can be fixed . Also takes 25 lbs off the nose and will work right . I learned similar things from Don Verity on transmission parts , a big pile of seemingly the same pieces ( as I had stashed up ) do not swap , keep all parts from any one trans together or else a fiasco .. That said if anyone knows about this , or maybe Mr Merritt already has it up somewhere , an explanation of the why —and physical differences —-would be really helpful . More so than numbers actually , although that helps . Posted as one 300 guy bitten by this ..
