They are a different shape and use a different latch system I have seen older ones on Rushmore bikes they kind of look out of place the lines don't match up with the bikes there is a aftermarket company making the 14 and up style I will look for the name 500 for just the pak then you have to buy the hardware but over 300 less than a hd tour pak and 09 mounting brackets will work but you need 14 and up docking hardware
