Right, LaPietra was the big one. Skids Caruso ran Chinatown for almost 20 years and was "asked" to step down so that Aiuppa could implement Angelo, who nevertheless continued to take care of the Carusos & the Rotis, as Aiuppa wouldn't dare snap those 1st ward ties. Taylor st was completely deactivated & all of its action shifted down Ashland to Chinatown, with LaPietra going from mere capo in Cicero to fully fledged king of Chinatown. Melrose park was sanctioned into Elmwood park, because Aiuppa did not want a crew to be based out of his hometown, therefore making Elmwood Park the second largest crew. Cerone was given Elmwood, making him 2nd in command, with accardo continuing to act as consigliere as he always had. Lombardo who was close with Cerone was given grand ave (at an extremely young age) after accardo & Cerone left for Elmwood. Keep in mind Aiuppa reached out to accardo/Cerone when Sam & Ricca froze them all out. Aiuppa had brought Cicero back into fruition which was deemed an impossible task (which is why Sam "gave" it to him, despite Aiuppa pleading for his hometown of Melrose park). Aiuppa/Cerone/accardo had been planning to overthrow Taylor st since the early 60s, they just needed to wait out their opening. Trust that if Sam hadn't gotten unlucky Aiuppa never would have became boss.

To answer PPs questions, like I stated, Aiuppa set up the outfit like a miniature version of NY if you will. of course Aiuppa & Cerone still maintained top control and final say in serious situations, but each crew boss was given much more power, and that particular crew boss's capos became more powerful, and the crew in general. Bosses were/are encouraged to keep to themselves and encourage their soldiers not to associate with soldiers from other crews. Rarely is a Chinatown guy familiar with the inner workings of the Elmwood park crew, etc etc. for example, if you'll read through, say, Nick Calabreses testimony, he said he had met Al Tocco & Marcello (and others) for the first time during his making ceremony, in his late 40s, had never seen them or heard of them previously. That was not uncommon. If a guy from Cicero gets popped, he wont be able to give them anything on any of the other crews, and due to the intimacy of his own crew/family probably wouldn't flip (hopefully) on them either. It was pretty genius, and allows the outfit to operate in relative secrecy until this day. Carlisi/Marcello & DiFronzo did a lot to continue Aiuppas vision as well. Infelice almost ruined it for everyone haha
