NV5600 questions

Gentlemen,
i have some questions about the beast NV5600.
First, does it use inner blocker rings on all the gears, or just 1-2?
Second, if just 1-2, why not all and, what would happen if inner blockers were used on all?
i know somebody has an answer, i just can't find it.
searched but could not find an answer.
any information is always good.
thank you for any help.

Only on 1 and two. Fairly certain it just has to do with the diameter of the gear. They are so large the inner blocker ring takes up the space between the outer and the hub. They won't fit on others as I don't think the gear has of enough of a relief on the backside. I have one apart at my shop I can double check and get back to you
