As near as I can tell, the stab is installed on the airplane with about 1 1/2 degrees nose up incidence.  According to the manual, it should be 1/2 degree nose down incidence.

Rick,

 

Bummer.

 

I think you should check the main wing incidence, washout, and dihedral before major surgery.

 

Some 320 360 fliers have replaced the original installed small horizontal stab with the larger one.  I am not suggesting you do that but they may be able to describe the procedures they used to perform the replacement and that may be useful to you when the surgery is begun to reposition the stab. 

 

Good Luck.
