From the description in one of your attached documents:
"Problem: Despite following KAI the placement of the nut place the holes too far forward to attach the empennage F-1249B-1 and F-1249A fairing and have the stabilator move adequately."

It sounds like you may need to trim the stabilator opening (wedge shaped window) to allow unrestricted movement. I ended up installing, marking, removing, trimming and re-installing several times before I was satisfied with the clearance. Just take small amounts off each time, then look to see where it is contacting.
