I have the same basic trunk on my foul weather/beater bike so my cargo won't get wet. Mine is solid black though, $6 at Wal Mart, I put Adel clamps around the rack frame then drilled through the bottom of the tub and used machine screws with fender washers to attach it through the clamps then put a layer of high density foam in the bottom. Mine has a carrying handle in the middle of the lid that rattled, I wrapped it with electrical tape until the tape was thick enough to wedge it against the side of the recess it sits in, no more rattle. I could have removed the handle but it makes a nice additional attaching loop for light items that are to big to go inside.
