For the Philadelphia family at least you had both Harry Riccobene and Rocco Scafidi as member sources providing information to the FBI. For the Colombos there was obviously Scarpa. For the Genovese family there was Valachi. For the Bonannos there was at least Willie Dara. For the Gambinos there was Alfredo Santantonio before he was killed. That's what comes to the front of my mind at least. All made guys.
