Front mount storage box for a Honda EU2000 help needed

Seems I remember some manufacturer that had 2 styles of receivers...low and high. The low one you didn't have to trim the spoiler. But for me, cutting the notch in the spoiler was quick and easy. I drilled 2 small ( 1/8"?) holes as a stopping point for height and width and then cut it out with a Dremel. It's fairly inconspicuous.
