That was Vincent Tarantola as I discussed early. When he moved back to the states, Luigi Greco sent one of his men from Montreal to DR, I believe it was Rizzuto but could be wrong.
Bill Bonanno was an ok Capo but he lacked a lot of qualities and was known to run to Joe. If he did not have Joe Notaro or Frank LaBruzzo around, most likely he would not have been able to wipe his own ass.
