Jerry,
I just spent the last few days installing my Metro roof rail seals and experienced same problems you had.
I was able to adjust the glass. There are adjustments for moving glass front to back in door; tilting the top of glass in or out; and raising the glass evenly when looking at it from the side. However the fit is not very tight, I was able to get a better seal on the passenger side, than the driver side. I used a piece of paper in the closed window to check the seal because my car is not put back together enough to give it the water test.
Another problem I've experienced is that when you roll the window up with the door closed the window grabs the seal in the roof rail to quarter window corner, where you show the extra material in your pictures. This causes the other parts of the window around the corner to loose its seal. But if I open the door and roll the window up, then close the door it has a better seal. But obviously this is not aceptable from a practical use standpoint.
My rear quarter window seals are from Steele, no problems noted yet, but again haven't water tested them yet. Steele's web site is kind of low tech, but they are very helpful if you call them. Here's the link:

Let us know if you use the Steele roof rail seal because I bet I will need to change out my Metro seals once I start using the car.
