Leaks around windshield gasket

I replaced both the windshield and the weatherstrip in my 65 cuda. I purchased the strips from Andy Bernbaum Auto Parts and while it does not fit much better than yours it does not leak. I did not install it but it looks like no "sealer" material was used. Do you have any rust under the w/strip? I would remove the w/s and start over, checking for rust or anything that could cause a break in the seal. Then re install using the current sealer for new cars as a back up. FYI most windshield replacement Co's will back up their work if it leaks. I also had the water drip on my feet problem and found the seal at the top of the vent box to the underside of the cowl was the problem. Hope that helps
