67 Dart Front Windshield / gasket problem

I've seen gaskets like yours on really old installations. You said it was installed years ago but you didn't say how many years?? It definitely doesn't look right. I know you want it to look nice but what's more important is whether or not it leaks. If it leaks then you need to have it replaced...if you ever drive in the rain. The upper right corner actually looks like the gasket has separated (not good)??
