UCA mounting bracket damage

Bigger pictures would definitely help, but either way you're going to need to reinforce the area with more steel. If its fatigue the metal has been weakened, and just pulling it back together and welding it won't get rid of the fatigued metal. If its rust you'll need to reinforce the steel thats not there anymore. Plus you'll have a hard time welding it up if its rusted because of all the oxidation already there.
