    Pictures would help, but you may need to add some extra foam gaskets between the window frame and the seal.

    I posted a picture not sure if you can see that well I'm not sure how that would work because the seals lock into a channel

    I've found that I had to put spacers/washers behind the weatherstripping channel in various locations to get the curvature to match the window better. Just 70s manufacturing quality...

    Thats a really interesting idea. Im about to have to pull my Passenger side seal down and do something because I have about a 1/8" gap between the window and the seal. So Im assuming you put the spacers between the inside (upwards-facing) window weather strip channel and the bottom (downward facing) area of the roofline?

    That's correct. Yeah I had about 1/8 gap as well... the roofline curvature just didn't match the window very well.

    Looks like you need some more tedious window & door alignment
    Lets see a photo from a few feet back from door

    To fix my problem (which was really bad on the Passenger side) I added an extra 1/8" strip of weather adhesive to the back side of the weather strip channel. The window now sits snugly against the weathstripping and I was lucky to not have to re-align the windows.

    So it goes like this:

    Body of Roofline
    1/8" thick weatherstrip (adhesive backed) - This is what I added
    1/8" thick weatherstrip (adhesive backed) - This is what I had already attached to the channel and was the OEM/factory thickness.
    Weather Strip Channel
    3M Super Black Weatherstrip Adhesive
    Weatherstrip

    Its basically a specific type of closed cell foam, which I believe is the neoprene type. I'm drawing a blank about that, so I would need to go check. (People make this closed cell foam out of polyethylene, neoprene, and some other type of foam rubber. I bought multiple products and compared the texture, density, and absorption tests. It was clear that one product more closely resembled what originally was on the car. I can take pics if you like.)

    Btw, I found a product at Lowe's that looked sort of similar, but the Auto-grade products looked to be better with better quality foam. I dont know how to explain it, but you could feel the difference in texture and weight, and they were basically the same price.

    Anyway... I bought this foam in a giant roll, because I cut all my own weatherstripping pieces. I also used this to cut a gasket that rests in between the body of the car and the chrome B-pillar trim and a few other things. I ended up with a lot over, but I've used it in various ways around the house and some projects here and there. It's been handy and I have used a lot of it.

    But it looks exactly like this:

    I think the Lowe's stuff (that I opted out of) was more like this - The Low density seems fine until you look at a different product side by side.
