NBS Rear bumper on a OBS stepside?

[FastOrange]

How do you figure?
Yes just looking at it it is the same bumper but the part under the tailgate is cut different on each one. Just like on the gmt400, if you were to try and put a fleetside bumper on a stepside it would not work because the bumper would not slip into the correct spot.
Look at where the bumper on shortntalls truck stops compared to where the one on this stepside stops.
