Does anyone know what years that 216/235 Chevy waterpumps can be re-built. I have seen old rebuild kits for mid to late 1940's but wondered how far into the 1950's the pumps could be rebuilt with a kit.

I've seen lots of early 1950's water pumps with the access screws on the back, SO is rebuilding success a matter of sealed bearings, new impellers, or what?
