The priests of SSPX would need to have their suspension lifted by the Vatican before a bishop could grant them faculties. I’m sure there are instances of a SSPX priest approaching a bishop and the bishop assisting him in regularizing him with the Church and then granting him faculties.
To the original poster: The bishop would need to give permission for the indult Mass to be held in an SSPX chapel. I seriously doubt that any bishop would grant such permission. It would seem that even if the priest is in union with Rome and has permission from the Ecclesia Dei commission to say the 1962 Missal, he still needs permission from the bishop who, as I said, would never grant such permission.
