Imagine what the car would look like if you didn't have that bumper. Glad you got through it alright, bend it back and go wheelin'.
Edit: I was looking at your pictures and is the main bumper brackets held on by a single bolt? If so, it was wasn't that the bumper wasn't strong enough, it pivoted on the single bolt. When you bend it back straight, plate the frame mount back to that first body mount and put in another bolt.
