Stop in for a cup of coffee

I just bought the vent hose from the defroster vents to the heater box if that is the ones you guys are talking about. I think I paid close to $6 for mine. They are some kind of plastic film over a metal / steel spiral. Mine is supposed to be 2.5 inches. Not sure what I have to do in the heater box end since at least one outlet is smaller.

The hose is supposed to be 6 feet long it says.
