Hairyknuckles,

No. I’ve never seen anything to indicate that Dellacroce cooperated but it wouldn’t surprise me to learn he “flirted” with the FBI at some point. (My assessment is only based on the files at MF.) I know the FBI does spread disinformation about mobsters, but the detailed newspaper article that came out after Dellacroce’s death stating he cooperated is pretty interesting. My own feeling is that the number of mobsters who dry snitched to the FBI at this time is much higher than is commonly suspected.

Nonetheless, according to FBI agent Bruce Mouw of the Gambino Family file (if you believe him), the Feds didn’t have any worthwhile intelligence on the Gambino Family for pretty much the entire decade of the 1970s. No active informants in the Family, and no nothing.
