Can you ID this Fresh Air Duct?

[David S.]

Hi All,

I have three of these fresh air ducts. First I thought they were C2 but now I don't think so. Also is this AC or non AC? Does it matter?

Thanks,
Dave

It's the adapter that goes in the cowl on the passenger side for an air condition C2

Good Evening David,

Lucky you! Nice to have three C2 AC Adapter Assemblies. These units are buried deep in the fresh air cowl underneath the Blower & Evaporator Assembly.

See: '66 AIM C60 sheet D4 and '67 AIM C60 sheet D5.

I'm including 2 shots from inside the passenger side foot well of a '66 and a '67 showing the attaching cable bracket that controls the metal door of your units. Maybe you can find those brackets and screws needed there?

I read this when it was current but never said thank you. Much appreciated for the info.

Best,
