windshield recommendations

I bought one of there's for my Dart. I broke my original taking it out. Instead of replacing the weathered OEM seal the po just butyled the hell out of it. The new windshield is thinner and made in Mexico but the quality looks good. I am concerned about the new seal sealing with the thinner glass. I'm going to have it installed by a local pro. After all my work I don't want leaks. Good price though $123.00
