I bought the part #2874548 about $30 and all went well! I guess it took me 1 hour? Remove old "locks" (that don't lock) and replace with new keyed locks (that lock), you just need to remove the old "hook" and grind off the "lump on it", then install the old hook to new lock and enjoy! And the semi-hard rear bag for the Touring model looks sweet, even the wifey was impressed with the storage in it! Part # 2847548!
