I can't seem to find how to replace the weatherstripping around my drivers side window. It is the big one that goes around the top of the window and I believe down the inside front of the door. The window sticks in the front inside section and the window will not go all the way up. It appears that the front inside section is bent somehow. The part is very expensive so I want to do this right. Yes, I've had the door panel off, but it is hard to tell where the bolts are that holds it in. Thanks...Bob in Ohio
