I had the same problem although I am not sure what the degrees were.  I
put the horizontal stab on and leveled it.  I also leveled the wings.  I
then secured the horiz tips so they couldn't move and them put the top
fuselage on and straightened the tail.  When everything was checked and
double checked I used many clecos to secure the top fuselage to the
bottom.  After checking the alignments one more time I secured the
Horizontal in place.  I verified everything was still level.  Wings,
Vertical, and Horizontal.  I then left for 24 hours and didn't even open
the door.  24 hours later I checked and nothing had moved.  I waited
another 48 hours before removing any of the supports.  It was all still
perfect.  I then removed the top fuselage and went back to work.

My plan now is to do the same process when the top is placed
permanently.  It will all tie together nicely and until it is all
together the airplane is very flexible.

I wouldn't cut anything in with the sternpost.

I also used a transit and a laser level.  Bryan
