i have a 74 dart swinger with a 318... i am removing my heater system and the port on the water pump that goes to one of the heater hoses..i need that to be blocked off somehow..i was hoping it would be threaded and i would just simply cap it off with a fitting however it isnt threaded..do they sell an after market water pump with just the bypass hose fitting and no heater hose port? or what im a little lost just need a water pump with out this port as i am running no heater, thanks
