I bought two different seals from two different vender's before going to Steel Rubber for the third one. Its a much better seal, softer and a better quality rubber. With that said it still leaked, so I installed a second seal behind it. I used a rubber coated foam like trunk seal, in fact I believe it came from a 67-69 Camero trunk. I just glued it to the cab and let it seal against the windshield frame. Now what leaks past the outer rubber, can't get past the soft foam seal on the inside. When the windshield is shut, you can't see any of it, and with it open, it looks like it belongs there. Joe
