Just don’t want the wrong information to get spread around the forum so I’ll finish my input by saying; I don’t know where you got your information from spot or the idea that it was a paper tube. This duct is the standard Neoprene/Polyester over steel wire coil duct hose that has been used for way more than half a century in most vehicles.

Call them on Monday morning and you will have your parts on Tuesday, that’s been my experience many times over the last two years.
