I have a '75 duster that I restored, and when it experiences rain (admittedly very rarely) the carpet gets wet in the front seat footwells. The firewall does not seem to be wet, only the footwells, and there seems to be a little water on the inside front edge of the doors. I have replaced the windshield gasket, the door gasket, the window gasket, and all the grommets and plugs are in place on the firewall. I also re-sealed the new gasket with silicone winshield adhesive to make sure it is not the windshield seal.
It almost seems like it may be coming in around the front edge of the door somehow, but I am not sure how, as the door seals are new and seem to seal well.
Any ideas? Are there areas on these cars that are prone to this problem?
The car hardly ever sees rain, but I plan on taking it to the Mopar Nats this summer; I don't want my new carpet ruined if it rains during the trip. Thanks!
