The tail fairing does not fit the intersection of the fuselage and the stabilizers on my plane. After pondering this for a while, I decided that the only way make it work was to cut it into multiple pieces then reassemble it.
The photo below shows how the right side was cut up to take the best advantage of the original part, and make it intersect properly with all the mating surfaces. Some more work on this side is required, but it looks like it will work out.
