Moving Damper Guide Rails

List,

Have a problem with a grand piano that regulating damper wires will not cure.
Finally observed that the guide rail is too far over to the right, and on 
medium to hard blows the nearby strings are vibrating, i.e. zinging, against 
neighboring damper wires.  It's obvious that this was seen at the factory, 
but not properly corrected.  What they did was twist the agraffes a little 
more clockwise to try and shift the left-most strings of the plain wire 
unisons away from the wires - but it still didn't work on all of them.
In speaking with the company's service tech, I learned that the piano is out 
of warranty already, having been an "Estate" piano with only 90 day warranty. 
 His suggestion, too, was to move the guide rail to proper postition, and 
re-regulate the dampers.  
Since these pianos were offered to dealers at a discount, we have to hope the 
local dealer will warrant the product now.  I think they will honor the 
customer's purchase, but I need to offer them first an estimate.
Anybody run across this yet, and take the time to effect the repair?  Using 
Newton Hunt's and Joe Garrett's guides to calculate, I can account for some 
of the time needed for the work, but I'd like to get a little closer in my 
estimate if possible, for the whole procedure. 
As always, 'ppreciate the help.
