Air tight cabin

[tgrace85]

Hi folks. I've got my second-gen getting scuff and buff before it heads to the interior shop Mar3. The car was "done" in September and got about 500 miles on it before I put it away for the winter and decided the paint and interior should be upgraded to the same standard as the rest of the car. The issue that's been gnawing at me though is how I can make the cabin as air-tight as possible. I know it has frameless windows and yes, I know the car is almost 50 years old and won't ever feel like something built new today. But I've got to believe there's something I can do to make the driving experience more comfortable. I built this car to DRIVE, and drive a lot. I just don't want so much air coming through the cabin. Any tips, tricks, or suggestions would be greatly appreciated! Thank you!
