Got hook and loop velcro one side is the hook the other is the loop makes a circle and rolls around and locks in. Few bashing and solid no major movements and the velcro is holding strong. I ran it through the 2 side holes and glues the fuzzy side of the velcro to the bottom side of mount. On the battery area i took the stop pad they gave and cut it to fit the entire area and glued that in also. So the soft side of the velcro also coushins the sides of the battery as well as secures them in place.

Got the hook and loop for 6 bucks at my local harbor freight. Also they have a nice xacto knife for 4 bucks have a nice rubber grip and makes body trimmimg effort less.
