I go crazy over noises and everything I have done, has helped a ton. I have heard that some people are getting wind noise after having their vents rebuilt. Mine are way better now. Also replaced all the other seals and door sweeps. Like Mattchu60, I got the upper door seal too, I just never installed them since the wind noise is better.
The other things I did, was while the cab was gutted to change interior color, I added Fat Mat to the floor and roof ( under the headliner). Fat Mat on the back wall behind the seat. Then the cardboard piece behind the seat, I put speaker carpet on it. Also lined the insides of the doors with Fat Mat.
On the cab floor: on top of the Fat Mat, I put the factory tar mat back down. I then used a foiled back jute padding. Then the new carpet, which had jute on the backside.
Behind the rear speakers, there is a space up between the rear panels. I put insulation in there.
