broken terminal on alt.
 

so i got a new alternator and battery haha i was fixing the connection on the alternator. Im talking about the black ground cable that goes to the one terminal on top of the alt. But the terminal broke the metal broke after i tightened it like a quarter turn and melted the bolt on there there is a stuff of melted bolt about a quarter of an inch thick. Any ghetto ways of reconnecting it to the terminal somehow? im desperate and i doubt napa auto parts will give me a new one.

any ideas?
