Yeah, that frame took a pretty good hit. Hopefullyl you can get the frame straightened. That may take some heat, especially that crunched front crossmember.) The spring steel bumper mounts can only stand so much bending, then they break like you found. But if you would have heated them they would have lost their temper (springy-ness.) Mine that were still on the truck when I got it were broken in a couple places as well, but I was able to find original replacements that were good. If it wasn't so expensive to ship, I'd send you the pair of repops that I have.
