Installing front windshield, '70 Dart tips?

I have a '70 Dart and need to install the front windshield. I have the new seal and have a basic idea on how to install the windshield using the string method. My question is, does the bottom seal of the windshield use a caulk to seal the rubber seal to the cowl top panel, there is no track or ridge? I will also be installing the rear glass. Any help/information or tricks of the trades would be greatly appreciated.... Doug
