was looking at the new bikes today while they installed my new tires. Can you buy the hardware, latches and hinges for the newer bikes and install on my model 2013? Looks like the kids are the same. And they are using the same holes for the hinges and latch

 

You can make the new bags work on the older models, but you need the complete bags as both the lids and bottoms are different from yours...

 

Yes the bag width and length is different from the pre-Rushmore as compared to the current 2014+ Rushmore's - thus while you can fit a Rushmore bag on a pre-Rushmore bike - you need the bag & lid to be the same years
