That front frame rail is a easy repair if you can find a good rail. I did one in my garage a couple of years ago. They really do just kind of fall into place.
If you go to page one of this post you'll see it's much more than a rail, lol. Torsion bar support is cheese, inner fenders are half bondo. I have a complete inner front clip as a unit from a '74 Dart I parted out last summer to go into it.
