What year? There have been several styles of rails over the years. I looked at Thule when I bought my 08 Outlook and they had nothing available. I made my own bracket which fit into the C channel and mounted my Thule square tubes onto those. I reused them on my 15 Enclave as they have the same channel. What does your channel look like. Brands which may fit yours are Thule, Yakima and Malone. Try Etrailer.com for good service.
