Lil' Johnny,
Pretty much any cast-iron water pump can be re-built, as long as the casting is OK, regardless of year.
It's more an issue of feasabilty for the jobber; I've gotten some rebuilt pumps for '60s vintage stuff, and they haven't even asked for my old core!
Depending on the application, some pumps are available on an exchange basis (Chevys), others have to be shipped out and re-done (like my '48 Chrysler straight-8).
Now this is going back about 12 years, but I needed a water pump for my '41 Chevy Dump
truck, and actually got a rebuilt unit from a local jobber ( I beleive the rebuilder was A-1 Cardone ). I've also gotten water pumps for old stuff from folks who carry Airtex
pumps.Check your local auto suppliers.
Rebuilding does require an arbor press, so if you're not so blessed, you'd be better to get a rebuilt unit or have some re-do yours.
