i kept the front and ditched the back... go under the front one as far as it was over the plastic ones.. there's a little hip in the bumper to raise it off the rail just a bit to go over turf.. only real reason i kept it is because the turf didn't really want to make the curve on the nose, and i figured if i had to fight it to get there chances were it wouldn't last... mostly just because i didn't feel like fighting it...
