Steinway Sostenuto Adjustment

Liszt,
 
A manager at a store that I contract for requested that I figure out what  
what was wrong with a Steinway B sostenuto pedal.  I should add that this  piano 
was restrung, refinished, new hammers, etc., but the work was not very  well 
done.
 
Turns out, the dowel that goes from trapwork to monkey was not there.   I 
fabricated a dowel that ended up being level with the keybed in the down  
position.  I put the action back in and found that the lifting rail was not  
regulated properly.  I could not get it right by sliding the rail in or  out.  It 
either wasn't lifting anything, or it was lifting everything all  of the time.  I 
did not feel comfortable messing with the height without  any guidelines.
 
Is there a trick to gauging the height and fore/aft position without using  
endless trial and error?  I know this was a recent thread, so I'll check  the 
archives as time permits, but I wonder if anyone has any handy advice on  this 
one.
 
Thanks in advance,
 
Dave Stahl
