I had a similar issue with rust & ripped metal.
One of my sway bar hangers off the frame rail actually ripped out a section of the frame. I would have figured that the hanger itself would have broke before the metal ripped, but DAMN !!!
I had to cut out a section of car & weld in a new piece. PIA !!!
