So the opening looks really ugly right now. I ended up cutting more than I planned because there were a couple of places that kept interfering. I'm now faced with a decision. If I raise the end of the bumper to make it more or less line up with the fender line, the end is at more of an angle than I may be able to correct with the hammer and dolly. On the other hand, if I square up the cuts in the bumper, it looks correct except where it meets the fender on the side. There may be some additional pie cuts to the end piece in the future.
