1974 Beetle Defrost / Fresh Air intake vents

To my knowledge you gotta get the used. Look at the classifieds see what you can find

Running out of luck, so I thought I'd aask the pros.
My 1974 beetle is missing the fresh air vents from the under the dash to the fresh air box, and the "Y" shaped vent for defrost? All three hoses come off the defrost "Y" connector. Are these vents available, or am i off to the junk yard?

Thanks
