What I was wonder in my question was can I put the header weatherstripping on with no top material or using adhesive for the window fitting process and then get it back off again to use adhesive for final assembly without breaking the pins on the weatherstripping. Or do you adjust the windows without this header molding weatherstripping on. My car, as I have said in another post, was COMPLETELY apart when I got it so all my windows and mechanics where all out and need to be adjusted to the top that was also off.
