 Same part number that I used.  Bored to 7/8 diameter the gears fit
 perfectly, and the system works very well.  I used this article as my
 reference.

  Attached is a .pdf file of the article in the Lancaie News re the
 gears
 for the rudder pedals. It has a reference to a source, but I don't know
 if
 they are still in business for the gears.
