You could cut it horizontally and attach one half to the hood, and one to the bumper. Make them overlap to the sides a half inch and they should stay flush pretty well. If not, throw some spacers behind them to help offset them from the grill. Overlap the bottom one over the top one slightly so wind doesn't catch the top one. Maybe make a flap on the bottom (opening down so the wind pushes it shut when driving) that you could use to stick your hand in and work the hood latch.
