In 1969 Carmine 'Fats' Taglialatela provided the FBI with a large amount of information on the Lucchese Family. Taglialatela, self-described Lucchese member, claimed he was sponsored by Paul Vario around 1958.

In August 1974 CI reported: "[Abinanti] handles all of Paul Vario Senior's operations since Vario went to jail [and] is assisted by Babe Vario. Abinanti reports to Tony Ducks [Corallo] on 116th Street [on] behalf of the Vario group."

D'Arco took over the crew following Paul Vario's death in May 1988. Shortly after his promotion a meeting of the crew was held in Canarsie. Purpose for D'Arco to meet with each member one-on-one and to put each individual's activities on record. Unable to attend, aged crew member Paolo Danna instead visited at his residence by D'Arco and Abinanti, who handled the formal introductions.
On February 6, 1989 Vario crew associate Thomas 'Red' Gilmore shot to death in Family-ordered hit. Against the wishes of Boss Vittorio 'Vic' Amuso, Abinanti and Lucchese Soldier Peter Vario, Paul's son, attended the wake. D'Arco was called in by Amuso: "Vic was steaming and he says, you know I told you to tell them not let anybody go to the wake. I said I did, it's done, what do you mean. He said, well, how come Pete the Killer and Rugsy [Vario] went to the wake. He says go ask them if they like wakes..I told them [and they] said they didn't hear."
D'Arco named Peter's son Joseph Abinanti as a participant in February 1990 murder of Lucchese Soldier Anthony DiLapi.
Around 1990 Vario crew associate Angelo 'Sonny Bamboo' McConnach accused of withholding money. D'Arco: "When Paulie Vario died, he had other people holding money for him..Peter Vario and Peter Abinanti [complained] that Sonny Bamboo they believed was holding $100,000 of Paulie's money [so] I went to Sonny's house and threatened him..I said, 'I'll kill you just like that. You're hiding money over here'. He said, 'I'll give it to Petey' and he gave the money back..I didn't get any money from that or anything. That was their personal money, Petey Vario."
