1965 Dodge Dart, Rain leaking in to the coupe

Thats it!

Got them 1/4 open, so when I spray water down the louvres, the water goes out the slots, and does not go down and out the vent door holes anymore. Off to a hardware store to find a 1 inch hose OD or something like that to connect to the shop vac so I can clean it up in there.
