I bought mine at Weco as well based on their size chart as well. And just like you, when I tried them out in the driveway they were too big. Brought them back to trade to trade for a smaller size but instead the guy fitted them to my truck, cut the extra links, took a cross bar out and now they fit perfectly. He gave me back the extra crossbars and links in case they ever need to be reinstalled. Great service.
