I don't have my book in front of me but look at the picture:

Set the bell crank so the top front face line of the bell crank ( the 
part that the pivot bolt goes through) is parallel with the cross 
over cable and the vertical part of the bracket is in line with the 
cable from the stick.  I recall that is pretty close to neutral.  At 
that point adjust your push rod length for aileron neutral 
position.  That should give you a 2:1 ratio of up to down aileron. 
Use a spacer between the bell crank and the aileron push rod to 
achieve a better angle of the rod to bell crank.  The critical part 
is to get them both set the same for neutral so the aileron travel is 
equal on both sides.  If you can achieve equal movement and within a 
degree or two of spec., that is probably close enough.  You can 
hardly see them move in flight.  Remember, the ailerons are 
"differential" so when one goes up 20 degrees, the other goes down 10 
degrees.  That keeps the ball centered in a turn with you feet flat 
on the floor.
