Just picked up a Yairi DY53 Canyon Creek. I started to adjust the truss rod to lay the neck back just a hair, and discovered the nut was missing. I just received a replacement from Yairi, but the truss rod is pressing against the upper part of the the cavity. I don't think I can get it to start threading on the rod till I get the rod away from the top of the channel. Can I put a little pressure one way or another to make the rod end move away so I can put the nut on, or do I need the help of a pro? I'm pretty comfortable with working on guitars, but this may be a bit over my head. BTW, it's way up inside the heel of the neck, and an absolute pain to even see whats going on. I do have access to a small snake camera that I'm going to use this evening to get a close up look.
