They had a beef? I've never heard that. Supposedly after the Galante hit, the hitmen congregrated at the Ravenite Social Club and were seen with Dellacroce but I don't know if the two men ever had any real "beefs" with each other.

Anyone else ever hear of this?

In the book Manhattan Mafia Guide: Hits, Homes & Headquarters by Eric Ferrara, Ferrara says an old timer told him Dellacroce and Genovese Capo Pete Defeo hated each other and had to be stopped from fighting at a casino in Vegas but says he wouldn't get into more since it was unsubstantiated.
