Hello there. I am not sure if the 80-045 is your original top guide on your door, but it is held in place with a screw through the hole at the bottom of the guide. If you are using this on a different door see if there is a screw at the top of the patio door panel that holes the panel together at the top. See if you could use that screw to mount the guide. Lastly you might need to drill a hole at the top of the door and use the correct diameter screw to mount the guide. Take note when drill be sure you don't damage the door frame or the glass in the door.
