I printed out the new page and finally found the change after holding it up to the old drawing with a light behind it. In Step 7 it now says to back the clevis rod end off only one full turn instead of two. Since I haven't re-assembled the tail yet it is an easy change to accomplish. Some folks may have to remove the tail fairings if they have been installed. It doesn't say anywhere that the change is mandatory for retrofit to completed parts, but I suppose it is a good idea. Sure would be nice if revised drawings included a shading or some other way to identify changes.
