Does anyone know where to find defroster ducts(tubes) to fit a Hupp 356 heater? The ducts on my 1962 Thiokol 4T8 are shot. My son 3D printed the connection from the duct to the defroster difusser. The end of the duct that goes into the heater box is similar to a rubber grommet, but is part of the tube itself.
