water leaks

Not 100% why the openings in the channel are are there, they are at the bottom near the cowl edge., near where the dash bolt in. I have read that you need to apply sealer when installing the new windshield gasket. there is info on this forum about windshield installation. if you do a search Im sure youll find it where they tell you how and where to apply the sealer. I also know from taking my windshield out there was alot of sealer to scrape out of the channel. That was factory .I still have the gasket and it has the old sealer on it. My car is a 1970 Im not sure of differences between it and a 74 duster.
