Diagram of parts for 1942-48 passenger heater

I just took one that looks like the photo apart, and was surprised to find three 5-6” sections of rubber hose between the heater core and the sheetmetal housing. The hose looked like sections of heater hose. I suppose I’ll try to reinstall with fresh sections of hose to keep things from rattling and rubbing, or come up with something more effective.
