wolfmandu Posted February 24, 2017 Report Share Posted February 24, 2017 Hello my fellow Datsun-heads. I have a 78 620 and I am missing the 2 duct hoses that go under the dash and blow the heat onto the windshield. Does anyone know if the same duct hoses from a 240z or a 280z from around that time will also work in my 620? Might they be the same size? I know a lot of parts are interchangeable and I cannot find the 620 hoses anywhere. Any help with this question will be much appreciated. I'm living in northern CA and it rains all the time. I really need the defrost to work. Thank you. Quote Link to comment
Anonymous Waffle Posted February 26, 2017 Report Share Posted February 26, 2017 When you say duct hoses, are you talking about the curved turn that comes out of the heater box, the long runner that runs up, or the Y-shaped come that leads out of the dash? Quote Link to comment
datzenmike Posted February 26, 2017 Report Share Posted February 26, 2017 Measure the diameter and get flexible ducting hose.and gear clamps. Like this... Dryer vent hose only smaller. Quote Link to comment

datzenmike Posted February 26, 2017 Report Share Posted February 26, 2017 Lets hope that Nissan didn't make one end larger than the other and that they are available. Quote Link to comment
wolfmandu Posted February 27, 2017 Author Report Share Posted February 27, 2017 Thank you everyone. I will try the new duct hose and fashion it to fit.. Quote Link to comment
