   I second what Rodger is saying only I can use a Renner USA or Tokiwa back 
action kit for 400 bucks. I can usually assemble it and have it fitted to the 
piano in a day. There's no mystery to this procedure it's just good pattern 
making and careful aligning. Hey, It's not beyond your capabilitiesd So why 
give Stwy all that money?
  I also make my own new pivot blocks and line up the underlever pivot pins 
in line with the flange center pins so everthing that moves rotates around 
the same center point. This totally eliminates the problems with the 
wierdness in the upstop rail adjustment , eliminates the ducking underlever 
syndrome which wears out the lifter felts if the tray is set to low and 
reduces the heavy pedal syndrome that Stwys have. I also ditch the brass 
pitman and put in a wooden one with a pin in each end, no more squeak. This 
part takes a little more time but it's worth it. I figure the whole retrofit 
and modification parts included at about $1750.00
