Why not just return them? What did they change on the stock '10 floorboards, from previous years? These are an excellent addition for the passenger, FYI, my wife loves them. Here's a free bump for a great product!
2010 baggers have a different size mount from the frame to the stock floorboard. The mount is larger and not as tapered as the old one. Kury rep told me that the new model number is 4353 and will be available in late May.

Slick,
Thanks for the reply. Went to the dealer and he said no problem on exchanging the 2010 for the 2009. Told me the MOCO switched because customers complained about the mounting brackets coming loose with only one bolt. So the 2010 has 2 bolts and is a little wider. The old ones have worked fine for me over the years. So now I have the 2009 brackets and the Kury 4571's fit fine. More impotant is now Mama is happy!
Thanks,
Mr_Bill
