Slant six fuel pump recommendation?

I'll be purchasing a new fuel pump for my 1974 Duster 225 slant six engine. The FSM says that the correct one for my car is a Carter MS-4844S. The Carter website no longer has this pump, but says to use a Carter M60577 (see photo from Carter website). If I go to NAPA, will I just be buying a re-branded Carter pump? Which brand would you recommend? Should I stick with the Carter pump? Thanks.
