which comes first...the windshield or the rubber seal

[materguru]

I have a 32 Ford Cabriolet and next step is putting the windshield in. This particular windshield is unique in that it seems to fit around the windshield frame then sit in the cowl frame. Or so Im thinking. I know there are a few special people here that could give me darn near expert information. All constructive information is appreciated. Bottom-line, do I try to affix the seal around the glass frame or the set it in the cowl frame first. The glass frame seems maybe the way to do it but i am NO expert on the subject especially being first time dealing with this car. thanks in advance
