according to a parts break down the 08 and 09 have the same part number for the input gear, as for the transfer gear i think the only difference is the shaft is a little more machined down on the 09 because I know you can fit a 5203 double roller bearing on it by just taking off the spacer behind the stock 6203 bearing.
I would ask your dealer or some experts on here, but i think it should work as long as you run the 6203 bearing
