Here is my 2014 Summit with Ionic running boards installed. Not best pic but should give you an idea
Not sure why the pic comes out upside down. If it fit this Summit should fit yours. Let me know if you need more info. I installed this same running board on my 2014 Limited I had. Got em from Ebay from the same buyer both times.
Edit to add that my buddy has a 2013 Overland with the exact same boards I put on my 14 Summit and fit both.
The Summit was just a bit harder to put on due to my sausage fingers not having as much room to maneuver due to the added trim piece. I did find an easier way to install the main brackets though.
Preassemble the bracket with the main bolt, add the washer and barely screw the nut to the bolt. You can then slide the bracket into place.
