727 Cooler Lines Help

hello i have a 67 dart with a cold case radiator and a 1980 360 727. Im looking for stainless lines for them since i have stainless all around the car already but i dont know what id look for. I have lines to them already but they cut them when removing the motor so even if i kept them i dont know what fitting size i would need for the cold case radiator or even the fitting size on the 727. Sorry im still learning its my first build. thank you

Just a heads up, stainless lies are hard to bend. Often those replacement lines will need some tweaking in order to get them to fit correctly.
