105/115 alignment problem

[Kevin Charles Trent <trentkc@domain.elided>]

I had my 73 spider aligned last Sunday.  i used a new shop that was close
and convenient and willing to work with me.  The alignment guy, who had
never done an alfa, agreed to let me sit in the car while he aligned and he
used the specs I gave him (recently posted from the Digest) which were:
- -.7 degrees camber; -1.7 gegrees caster, and .06 toe in.  He spent nearly
two hours and got all the settings correct (I could tell the manager was
getting antsy with the time being spent).  After two days &100 miles of
work commuting  the car seems to handle, track, and turn correctly.

Here is the problem:   Although the car is set up correctly, the steering
wheel is crooked.   I have had this problem before with other alignments
done by technicians unfamiliar with the Alfa alignment technique, and I
believe that the problem is caused by using an incorrect method to set the
toe in  (correct??).  

This is my question:  Can someone provide the proper method for setting toe
in, so that the steering wheel is straight?  The method described in my
Haynes manual is:
  
1. Set steering wheel to straight ahead position. 
2. Set the front wheel on the steering box side to straight ahead position
by using the track rod. 
3.  Measure the length of the track rod on the driver side, then set the
track rod on the passenger side to same length. (I don't get this step, but
suspect it is related to the crooked wheel problem.  And what about
collision damaged cars?)
4.  Use the center tie rod to bring the wheel on the side away from the
steering box into the straight ahead position.
5.  Finally, turn the track rods by equal amounts on each side to set toe in.

I suspect that the steering wheel problem is caused by setting each side to
straight ahead using the track rods, then using the center tie rod to set
toe - although this method seems logical to me, and the one above dosen't.
I just want a good alignment with a steering wheel that points straight
when it is supposed to.

I hope to return the car on Thursday, and would like to take the technician
the proper method as described by the Digest's expertise.   BTW, are there
other (more common) cars out there with a front end design that is the same
as 105/115?   Thanks in advance.
