5/16" wide ribbon seal (also called butyl tape) is the way that the factory did it. Black urethane is what newer cars use and what most glass guys carry in stock. They say they can make it high enough for the trim to sit correct but I yet to see that happen. They also try to tell you that the urethane is better and your window won't pop out....LOL... my 30+ year old car still has it's glass and the Butyl tape is still holding fine. Good luck...
