what's the thickness of this aluminum sheet? 2 / 3 mm?Only one bolt hole you can attach other end with industrial Velcro only trouble I find is if I remove battery the glued bit comes off as it's always rainy here's so use another piece of Velcrco I used it with bolt only for 800miles and it was ok but not enough thread in my opinion . Still look for bolt M12 x 1.25 pitch 19mm the one for battery but I would get another 5mm and cut if needed. Other hole lines up with drain hole .
