Watching Godfather of Harlem it never really, ever occurred to me of how racist members of the Italian mafia could of been in those days, so my question is was it common among mobsters to be apart of the KKK?

No, Italian immigrants and Catholics were targets of the KKK, not members. This older answer should be of interest on this topic.
