Let's talk about wind noise

[SFTorange]

After getting my truck back on the road, I've become hyper-sensitive to the various noises it makes when I drive. I'm always waiting for something to go wrong (like when the alignment shop didn't tighten my wheel!!).

As I drive up to 45 or 50 mph, the passenger side window makes a pretty loud whistling/blowing noise. Obviously, this is a 45 year old truck, and it is going to make some noise, but I'm trying to figure out what is normal for a vehicle with new weatherstrip. Ideally, I'd like to eliminate the whistle, but I don't know if that is too much to ask.

What do you guys think? I drove around a lot of years with dry-rotted worn out weatherstrip, so I know how loud it can be!
