That was exactly the response I got in October to almost the exact same inquiry, except with respect to a JSW wayback cargo liner. I had no patience-- buying new stuff for a new car so need it RIGHT NOW NOW NOW!!-- so I tried to figure out if the 2014 was configured differently than a 2013.
After concluding that it was not, I ordered the 2013, so I could get it RIGHT NOW.
The packing slip showed the 2013 mat, but there was no way it would fit. Again, I have no idea if the 2013 mat was different, or if it wasn't really a 2013 mat.
There was a phone number on the packing slip for returns, so I called and told them my tale of woe, and the woman on the phone found the part # for the 2014. Looking back, it wasn't weathertech that I called, it was CarID.com-- which is a retailer for weathertech.
Anyway, the CarID website still doesn't show the 2014 year for the JSW. But there it is in the back of my car, covered in mud and dog hair.
