Horizontal Stab Angle of Incidence

I am a point where I am closing up the turtledeck and I cannot find what angle of incidence is called for on the horiz stab. The plans call for 1.75" between centerline of upper longeron and centerline of the connector tube at sta 137. If that is true, then the stab is parallel with the upper longeron and there is no incidence. However, in Hales "construction guide" he says "Horizontal tail surfaces are now installed and made parallel with the wings". But the wings are at 1.5 degree incidence.

Can someone give me some insight to this apparent conflict. Any ideas?

Much appreciated.
