My second 1965 Dodge Dart.

Ok, the vent is down, I have no clue how I managed to miss rod number two. But, there is no hole in the sheet metal that faces down in towards the coupe. I mean under the dash. However, there is a ... well, I assume the black stuff there at some point have been a foam rubber gasket / seal of some sort. It is hard, and someone has used some black sealant around there. Like black silicon or liquid nails, or caulking. Whatever it is. And, it seems to me they have put some around without taking down the vent, just tried to smear it on on the outside.

But, as we all know, there is a metal tube, 6 inch or whatever that sticks up there. So, this still puzzles me. The tube sticks up there, and if it is water tight between the tube and the plate it is welded to, it should not have to be a foam rubber seal on the vent to keep the water out. Or, is that really the issue here, that the tube is not watertight where it is welded to the sheet metal ?
I have troed to take some pictures with my phone, but that did not give any good pics, it does not focus well.

Anyway, I need to get my vacuum cleaner up there and suck up the dust and whatever around there.

Will be back later with more. Maybe I will get some good pics.
