I don't know if this is the right place.  I have a 84 skamper popup.  The top of the door where it attaches to the roof is broken.  I can't find a replacement part for this.  The door folds up and attaches to the roof when not in use and down and attaches to the bottom part of the door.   I need the part that attaches to the top of the door and to the camper roof above the door.
