artic fox 811 on 2005 dodge ram 2500 diesel short bed??

So we still have the tie downs ( brand new ) from when they were put on the 2500. ( minus the underneath bracket that we decided to leave on old truck. So I'm wondering if they will work on new truck w just some new underneath brackets ?which I assume would need to be longer due to the Dually. Asked the dealer to find out about this for us but of course we have not heard back from him.
