Matt, if your frame where those bolts are attached isn't beyond the edge of the bolts, you have more serious problems to worry about than the bumpers! Once you're contacting that frame area, no problems there.

Also, like I said: they won't be measuring center-to-center. It'll be point-to-point, so you would probably have been able to pass as you were, if you could have convinced your inspector that the bolts were part of the Frame Perimeter. That convincing would have been the hard part...
