After you have measured the width as shown in caption No. 1, you will need to get some 3M blue striping tape in 11/42- and 11/44-inch widths. First, apply the 11/44-inch tape 511/42 inches from the back outer edge of the hood. Then apply the 11/42-inch tape to the inside of the 11/44-inch tape. Another 11/42-inch strip of tape will need to be applied to the outside of the 11/44-inch tape.
