the la family worked with la eme back in their early days. That obviously isnt the case now as that families now extinct. but i doubt theres much partnership now as the mexican mafia pretty are one biggest oc groups in cali now anyway, they got power in most the prisons and through the gang leaders on the street who are often members.

On the east coast, theirs obviously associations with biker clubs such as the hells angels and pagans. The only other groups i could think of are the aryans and junior black mafia. But it seems that most alliances are opportunistic such as the bloods/luchesse thing came up after the pernas wanted help or backing from a bloods leader in prison after one of their associates was being shaken down by a blood on the street.
