I got a 2013 Jeep Wrangler soft top and I cannot figure out how to fasten my side windows next to the door. There isn't a place to attach the windows to the B-Pillars, at least that I could find. Is there a retaining bar or some accessory like one that the tailgate has but for the side windows? I included pics. The windows flap around every time I drive and it's really annoying.
