I picked up a 2015 Sahara this weekend and it has the hard top only. I found a complete soft top kit on Craigslist. Are all JKU soft tips from 07-15 the same? The ad states that they believe they are the same but I'd like to try to confirm that before driving the 2 hours to get it. Would hate to have to buy it only to have to sell it again. TIA.
