SAC sizing die compatibility

Been eying the SAC modular die and recently was told their dies won’t work in a Dillon 550 press, which is what I make my match ammo on.

Can anyone confirm one way or another on this?
They work but you need to run the lock nut from the bottom, not the top. It's tight and kind of a pain in the ass when adjusting bump but it works. Mark Gordon actually has a video on how to run his dies on Dillons on YouTube.

Can you link that video? I’ve tried looking for it but can’t seem to locate it….
I did see he mentioned making a decapping expander mandrel but I don’t see it on their website, did that ever come to fruition? Cause I could throw it on the rock chucker and do it all in one step if they did.

I'll have to dig it out of my YouTube history, I'll search...

Here is the decapper, mandrel:
