they were originally Vatican 2 Catholics and they still attend Byzantine Catholic Masses for Sacraments. So your assertion that they've never received the Sacraments is blatantly false.
And using Feeneyite as a pejorative is a bit odd when there are absolutely no ex cathedra statements in favour of BOD but dozens against.

Sorry for the above incorrect statement. However, the fact that the Dimond Brothers (who possess a "holier than thou" attitude towards all non-Feeneyite Catholics) still attend Byzantine Catholic Masses for Sacraments makes them hypocrites, plain and simple. 

They are receiving sacraments from Novus Ordo clergy in Novus Ordo churches, then have they audacity to continuously and publicly say that all non-Sedevacantists are damned to Hell. Thus, they are receiving sacraments from NO priests who are damned to hell. You would think that they would at least go to a Sedevacantist mass to receive Sacraments (since they make a living trash-talking the NO Church). Since they keep going to NO Churches to receive sacraments, why should anyone take those 2 seriously??

Pope Pius IX spoke on BOD (check Denzinger). I suppose the Dimond Brothers, as well as other Feeneyites, thereby consider Pope Pius IX to be a "false pope." 

Also, Fr. Feeney was excommunicated "for disobedience and not for his position"-- that is true. However, that's only half of the story. Feeneyites usually fail to mention the other half of the story: Fr. Feeney disobeyed an order to come to Rome and defend his position (because even he knew that he had no theological leg to stand on and that he would be vigorously questioned on his untenable position by theologians much more learned than he).

Pope Pius IX spoke fallibly about invincible ignorance, which is different altogether to modern BOD. Yet even then Pope Pius IX was not saying that those that die outside the Church attain salvation, but rather that those who are invincibly ignorant are not guilty of the sin of unbelief and will be guided to the faith before death by divine light if they live virtuous lives. This is the same position St. Thomas Aquinas held. 
Every time Pope Pius IX mentioned invincible ignorance he preceded or proceeded it with a repetition of EENS, that no one can be saved outside of the Catholic faith. Unless you are proposing Pope Pius IX was a scatterbrain who contradicted himself from sentence to sentence on the same issue in multiple encyclicals, then it is clear that when he said:

 they who labor in invincible ignorance of our most holy religion and who, zealously keeping the natural law and its precepts engraved in the hearts of all by God, and being ready to obey God, live an honest and upright life, can, by the operating power of divine light and grace, attain eternal life, since God Who clearly beholds, searches, and knows the minds, souls, thoughts, and habits of all men, because of His great goodness and mercy, will by no means suffer anyone to be punished with eternal torment who has not the guilt of deliberate sin.

he meant to reaffirm what St. Thomas Aquinas taught, that virtuous heathens living in invincible ignorance will be guided to the faith. 
Even if Pope Pius IX was indeed a self-contradictory scatterbrain who preached that those who died outside the Church could be saved, while reaffirming the next sentence that they could not, it still would not prove Baptism of Desire not even to the extent of invincible ignorance, as it has still never been defined dogmatically. Never, not once. And for every Pope in the last 150 years or so who has taught it to some extent, there are many many more from Church history who denounced the idea completely(many Popes even saying unbaptised catechumens are damned!). 

I didn't know that the sede Dimond Bros. receive the sacraments from Byzantine Catholic Masses. So, they do not attend traditional Masses by traditional priests. That's very strange.

They used to attend byzantine masses suggesting to go late just for the eucharist but I would be surprised if they still do. I believe their position now is that there is hardly a priest in the U.S that you can receive the eucharist.  I remember sending them an email a few years back about a priest i thought was good enough, they said it would be acceptable to receive the eucharist but told me (angrily)it was a mortal sin to give money , this I disagreed with and I don’t believe they have ever proven their position using Catholic teaching
