I've had a wind rattle on my car for awhile now whenever i'm going over 50 mph. I finally decided to do something about it an noticed the t-panel was bouncy when I pressed down on the drivers side/windshield section. I took the header panel off the top of the windshield and noticed the t-panel can bounce pretty freely. Is there supposed to be some foam up in here? What have other done in the same situation?
