Staples in the belt line
I have found a simple way to do this. First remove the old felt, compare it w/ the new one. Align the new one on the door panel. Using a small "needle nose / long nose" Vice grip Part#6LN, clamp the piece in place. Drill the first set of holes, starting in the center. Push the first staple thru the holes. Take the vice grip, fold the lip outward and clamp the staple in place. Take a small hammer or other tool and bend the staple tips toward each other. Now undo the vice grips and use the vice grips to bend them down. It works great and takes just seconds per staple.
