M52A2 defroster hose connection

[rcflyer70]

How did the defroster hoses attach up under the dash of the M52A2 so I can effectively defrost my windows in the winter? I had the cab off the truck last summer (totally stripped) repairing numerous rust holes but never thought to investigate this at the time. Now its assembled (purring like a kitten) and I was in the process of putting in my arctic heater in and hooking up the hoses when I came to the realization that there was not a destination for the hoses.

Any help would be appreciated.

Don't know if this helps Should be a duct for each side.

Any idea where I could acquire a set?

Should be the same as the m35

I've looked in M35, M54 and M939 parts manuals and cannot find a reference to them - frustrating!
