Just some input here.......I just bought these as well as the outer rubber lower window seal.......you lay your arm on it when you roll the window down all the way and rest your arm/elbow on the door.
They helped big time on being able to roll the window up and down EASILY again! I love how my windows work now!
Here's how some of your window channels look when they have dried up and are now too short between the 2 sharp bends (one at the front of the glass by the mirror mount, and the other at the top rear of the door, as the pic shows) in it and therefore it will get "re-shaped" when you roll the window all the way up, or down.

Fits good in the corners now!
And the outer rubber window glass seal.
How many of the original rubbers are this flexible?
