Was it a change in position?

According to Father Cekada in the link posted above, when he asked Archbishop Lefebrve in the 70's, he considered the NREC to be invalid.

So yes, change in position for the SSPX.

Did you ask me because you think it isn't a change in position?

Well, I don't put much weight in Fr. Cekada, God rest his soul.  My one and only experience with him was not good.  +Dolan apologized to me for Fr. Cekada's behavior.

Archbishop Lefebvre's Letter to Confused Catholics:

(Archbishop Lefebvre himself said this about the new orders:)

"Everything is bound up together. By attacking the base of the building it is destroyed entirely. No more Mass, no more priests. The ritual, before it was altered, had the bishop say “Receive the power to offer to God the Holy Sacrifice and to celebrate Holy Mass both for the living and for the dead, in the name of the Lord.” He had previously blessed the hands of the ordinand by pronouncing these words: “So that all that they bless may be blessed and all that they consecrate may be consecrated and sanctified.” The power conferred is expressed without ambiguity: “That for the salvation of Thy people and by their holy blessing, they may effect the Transubstantiation of the bread and the wine into the Body and Blood of Thy Divine Son.” Nowadays the bishop says: “Receive the offering of the holy people to present it to God.” He makes the new priest an intermediary rather than the holder of the ministerial priesthood and the offerer of a sacrifice. The conception is wholly different." (p.54)"
