I just did a test as I wanted to see just how much air is coming in around the doors with just the cab seals and no door seals. I sat in the truck and had the wife use the shop vac and blow around the doors all the way around. To my surprise I did not feel any air coming in. I thought for sure I would feel some air coming in. I assume the shop vac just doesn't blow the air fast enough to simulate driving 50 mph. I opened the hood and had the wife blow at any wires going through the firewall. At the center of the firewall is the main line of wires coming out and I could feel some air coming in. Just thought I would feel more air coming in around the truck. Even tried blowing around both air vents. I got nothing. I know these old trucks are like a tin can and cutting down the noise was not in the picture back in the day. I'm hoping the amount of wind noise coming in at 50+ mph is dampened just a little once the door seals are installed.
