Heater and defrost

[stretch1940]

Does anyone have a source or part numbers for the series 2a defroster (tubes-ducts) and the 4 1/2 inch heater intake duct.

I've used Greenline's TPR duct before for heater ducting.  https://www.greenlinehose.com/buy/product/tpr-225/25131?ID=/Hoses-by-Application/Ducting-Hose/dept-30V
