sand it down and use some jb weld then get it rebalanced any place that fixes it is just gonna dismount it weld and sand it. it's on the inside I wouldn't worry about it. just sand it down and have someone put a 10 dollar weld on it or jb weld will be fine.
disclaimer only part of my answer is honest the other part is funny but would probably work.
