How to minimize wind noise...?

Hey everyone, I've owned my '72 Scamp for about 5 years now, courtesy of my Dad. It's come a long way from how I received it, but I'm still battling simple issues like wind noise. I've replaced the vent window seals, door seals, roof rail seals, and felts. The wind noise has gone down quite a bit compared to beforehand...sounded like I was driving a house with a door open in a wind storm before...but, I'm still at a loss on what else to change. Would the windshield gasket cause this issue too, or is it expected with these cars to have a measureable amount of wind noise?

I'm kinda at a loss here where to go with it...any suggestions are certainly welcome and appreciated. Thanks FABO
