I got it fixed up. I welded up the oval part and used a die grinder to shape it and then ran a 1/2" drill bit through it. Before I started I put a new 1/2" pin in the hole and it was actually still pretty tight. The old pin broke off and was only held in from the top. So everytime I angled the hitch or was rough on it while plowing, it caused the hole to oval on the outer edges, but the center of the hole was still round.
