1965 273 waterpump fittings?

So I’m replacing the waterpump on the 273 65 Dart and am looking for new bypass and heater core hose fittings because the originals already look like they’ve been replaced many times and are heavily corroded. I searched the site for suggestions and found some leads but the threads are old. I searched some parts suppliers but they don’t say they will fit the new FlowKooler water pump I sprung for or a 65 though I expect a 70 up LA would be the same. The pump came with a threaded insert for the bypass but nothing else? Does anyone have a new replacement solution? I would also gladly buy older ones in good condition if anyone is willing to part with them.
