I can get you an FBI file on Michael
Here you go
http://vault.fbi.gov/thomas-ryan-eboli/Thomas%20Ryan%20Eboli%20Part%202%20of%205%20Maryferrell has a more concise version that other users have posted. Can't find it right now but Tommy Eboli and Mike Genovese were meeting to discuss Carlo Gambino walking all over them, and Eboli's frustration with Jerry Catena as acting boss. Mike doesn't say much but clearly he was in some high level discussions. I believe he was very low profile.
