In principle the strap prevents the flap from rearward movement thereby preventing contact with the lugs and stopping the strap from being pulled into the tunnel. What I did was the following. Go to a home center (Home Depot, Menards, or your local hardware store) Buy nylon strap material approximately 3/4 to 1" wide ( similar to width of your tie-downs) I cut a length of strap to about 18-20" long. On each end I punched holes about 1/4" from the ends. But first sear (open flame) the ends so that you don't fray the nylon with wear. When buying the nylong also purchase a brass of steel eye-let kit, the kit would include brass or steel eye-lets, a punch tool and a flaring tool. Punch holes at the ends of the strap and install the eye-lets. Obtain a long headed 3/16" rivit and on one end (outside) add a large headed washer and on the back side of the snow flap add a back up washer and install accordingly. You can also use a bolt and nut if you would like.... Mine mounted through the flap below the Arctic Cat wording, just for a point of reference. Hope this helps... Good Luck and happy new year.
