Here is when, the swap was a one on one thing with the customer, Deere, & the Dealer, if you have the old style axle and are not happy with it during mowing (many, many are happly with the old style) you are going to have to sit down with your dealer and ask them to plead your case to the field Rep. for your area, if they won't, or you get a no, it's time to move up the food chain and call Deere yourself. I believe a good dealer could still get this done, or maybe get Deere to split the bill, or Deere buy the parts, and you pay the labor.
Good Luck !
