This is what I finally found for our 2012:

Don’t know if your 2014 is the same.
Of note, I had an issue with the longer driver’s side wiper (original and all replacements) swiping too far - the tip would run up unto the windshield seal and trim. I went with two passenger side (24 inch) blades rather than using a 26 inch blade on the driver’s side. Solved the over-swipe issue and has plenty of coverage.
