Not sure how to deal with the broken bolts. Mine came off easily. They will clean up nicely. Take them off, wire brush ( sandblast is even better) and prime them and paint them. I put them back on using a rubber insulator between the steel and aluminum. Take them apart, straighten any bent arms. Get some new teflon locking nuts and you're good to go back together. Just like new
