Here's what I got from the 04 parts manual.
Hose (right vent) 05097789AA
Hose (left vent) 05097787AA
Hose, small (left vent) 05097790AA
Hope that helps, there is Mercedes parts cross reference guide in the documentation collection, if you look there, you may get lucky an find those numbers cross.

Edit ; by George ,I think you got it!
