The LA family that was the more powerful was know as the Mickey Mouse Mafia and had at least almost 50 made men at its peak while the Lanzas in Frisco and the Cerreto in SJ had almost 30 made men. There was never a close relationship with the 5 families and them went to the Outfit fo settle the disputes. I doubt Gravano or even Gotti ever had meeting with California made men because was basily done in 1986.
I remember reading in many articles that the Bonannos had oversight over San Jose and San Francisco, alongside having a West Coast (spread evenly between AZ and CA) crew of 20 wiseguys.
At some point, Bonanno felt DeSimone wasn't doing enough to expand the Mickey Mouse mob, and sought to replace him with his son and 40 additional wiseguys. That and his plot to kill Lucchese, Gambino and Magaddino is what led to the rigmarole in the 1960s.
