What's the story with the guys leftover from the Amuso/Casso era who never ratted, remain alive and are free?

Do Lastorino, Baratta, Zappola and Avellino have any roles to play in the current family structure?

Baratta had a sit down with Crea over a table at Rao's and won.

Surely that means he has some influence.

I imagine what went down with Lastorino's son didn't do him any favors.

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
