I think Lombardo may have been jealous of Eboli friendship with Chicago, Bufalino, and Angelo Bruno. That is a possibility. For Gigante, both him and Tommy lived in New Jersey, and Eboli was trying to gain influence on the Jersey docks, mainly Tony Pro territory, not only that but a couple of Eboli people were forcing his jukeboxes on some of Gigante friends who already had an understanding with Zeccardi. Tommy was stepping on a lot of toes in New Jersey and only know one sit-down that happened and dont know the details, most likely not good. More and likely there were other sit-downs.
