Hi guys, my trusty '95 is starting to buzz/flutter around the driver's A-pillar at highway speeds. It's quite frustrating to pinpoint, but it seems to be coming from outside the car where the trim piece fits along the A-pillar of the windshield. I've taken out the trim piece & stuck foam on the inside (TSB), tried bending it to fit tighter against the glass etc, but no avail. Sometimes the noise sounds like it's the dash vibrating near the windshield, but when i place my hand there, it makes no difference.

Would love to hear some suggestions, I know the car has high mileage (450k kms or 270k miles) and various rattles & wind noise, but this buzzing is very annoying
