I am not to this point yet on mine ( I have the same issue with my lever) but I have this guys info saved when I get to that point. Maybe call him and/or send him photos to see if he will quote it and what kind of guarantee he has on his work. You can send pics directly to him for a quote on his Instagram page.

https://www.instagram.com/potmetalrepair/Keep us posted if you decide to use him. Finding someone that can do good pot metal repairs would be a good friend to have.
