It wasn't in the 70's as it says that gotti became boss which happened in 1985
I don't think the book said he was the boss on '85. It said Gotti was running the Bergin crew (in place of the ailing Fatico) and a little later, also running the Ravenite (for Dellacroce) shortly after he was released from his second stint in lockup.
