I don’t know if this counts since he wouldn’t be an SSPX priest but if I remember correctly a couple of years ago fr. Robert Morey, a NO priest, visited the SSPX chapel in Charlotte NC, and I’m not aware if he’s “helping” the SSPX but he’s still part of the Diocese in Charleston in SC. He could potentially be another name to add to the list.

Thank you. If there's a chance he might show up at an SSPX chapel and catch the faithful unawares, we can put him on the list.
So, one of the little pieces of gaslighting they are doing is to blame these questions about the new Rites on "sedevacantists". I can assure you that a significant number of non-SVs have questions about the New Rites. I know an independent priest who considers them to be downright invalid, and he's no sedevacantist. Several of the Resistance priests also question the Orders. AND, when our independent priest was sick, every week I would get questions from half his chapel (non of the ones asking me being sedevacantists) to find out which priest was coming in and whether he was validly ordained (at least conditionally).
Just in that particular chapel alone I saw first-hand the consternation it was creating for the consciences of the (non-sedevacantist) faithful, and it's absolutely unconscionable for SSPX to just tell them to shut up and accept their decision ... when of course they disobey the man they hold to be the Vicar of Christ, and then say we must trust the men who became priests and bishops, considering those priests and bishops who hold the opposite view to be chopped liver I guess.
It's clear what's going on and why they're doing it. It's not some matter of principle or Catholic Sacramental theology. It's purely political, and they're willing to sacrifice souls to impose their opinion.
