Are we 100% sure that Joe Gallo was made ?
I've never seen much stuff about his induction and made or not, he had enough power to run his crew so I always thought it didn't really matter.

There is no doubt about that at all. Both Larry and Joe were inducted into the Profaci Family, before later rebelling. Their kid brother Albert was the only one not inducted at that time. But even he, years laters, is said to have been brought in by the Genovese.
