Bob,
I bought a set of rudder gears from a gear supplier in Dallas/Ft. Worth area.  I had to place the order them through a local supplier, a bearing house, as they don't sell direct to the public.  I will look through my receipts tonight to see if I can locate the mfg. & p/n.  They will need to be bored to the proper diameter though.
