HI, I have this weather stripping in 11 windows. It goes into a groove in the rear facing piece that catches the front of the window as it's closed. Not sure how to install it. Also, the measurement in both directions is a hair more than 1/4". Therefore, I am thinking it's 9/32" x 9/32". PLease take a look and let me know your thoughts. Also, any idea on how to install the replacement without messing it up.
