The "no no" about the 1962 missal, is that there was at least one change made to the canon of the Mass. There might be more, I don't know, but the least that was done was that Saint Joseph was added to the canon, against the wishes of the infallible docuмent Quo Primum.
Call me a purist, but it does say very clearly that NO ONE is allowed to add or subtract or change the canon of the Mass.
