Hey,
I apologize, but I just double checked the part #'s with the manufacturer website and it looks like the 4" ovals which I have are not the correct length for the 14's. For a 2014 crew they are listing a different length board, but the brackets are still the same. I am not sure why the 3" round side bars fit from 01-14 but the ovals only go from 01-13, I am guessing it has something to do with the mounting hardware on the ovals.
