I have some extra cross bars I can sell you. I think I have 2 to sell. I would have to ship them to you. You can actually buy these online. I just happened to come across your thread here because I am thinking about selling my entire OEM roof rack and wanted to know the going price.
The reason I have extra cross bars is because my roof rack cross bars got stripped off by a idiot parking garage attendant. Anyway, the insurance replaced the whole roof rack and I have extra cross bars.
I am honestly not sure if I have only one extra or two. Let me know if you are interested and I will check. I will certainly price them lower than the new ones you can buy online.
