luke,I found out from my dealer today that a 200 platform can't be retro'd,too many differences,only a 900.Of course,you can buy a whole new auger for either,but the cost of that makes it less inviting.What I am saying is that unless you have a 900 series,there is no need to go further.If you do have one,I will try to find out the guy's name and number.Neighbor told me that the guy started doing this for a dealer that had ordered some new heads without the full "treatment",and they had to try and scramble a way to not throw away brand new augers.I don't know if he is still doing it.let me know.
