I recently attended a 212/412 technical course and the major components on the 412 are all retro-fittable on the range back to the early Hueys. Now this obviously does not include the bits that are DIFFERENT, ie swashplate upper ring (4 p/links), mast etc etc.
My point, if a bit round about is that the greater majority of 222 bits should be interchangeable with 230/430 series barring the obvious differences. Both series are derivatives of an earlier type and evolved to what they are today.
Obviously this is an educated guess on my part re the 222, but I am sure that someone out there will know better for mine and everyone's enlightenment.
OTY.
