I have my heater core in the shop to get re-cored. original owner had blocked off the return hose from heater core and capped of the return on the water pump. Iwas on EBAY and someone has new Y Block waterpump nipples  1954 -1959 for 14.95.

Was curious to know if anyone had other resources to locates these or a different approach something that can be purchased thru Napa or other auto parts?

Thanks
