Why not give them a call? If Fr. Ward is the same man he was when he was with the SSPX, I'd be very surprised if he'd have anything to do with any other group, resistance or otherwise, but heck, who knows, surely it'd be worth a call I think.
I can only guess, but I think he doesn't really give a hoot about what goes on in the SSPX, my opinion is he remains happily Independent since he left them, and since he's been like that for +40 years, has no intention of changing. I still think it's at least worth a phone call.
