So I bought the most barebones SE I can get my hands on. No factory-installed roof rails. However, I would eventually like to get a roof rack. Can the factory rails be installed after the fact? I'm not talking about the cross bars, I'm referring to the lengthwise rails that the crossbars would attach to. Searching online, I'm only seeing the cross bars, for either OEM or aftermarket. Yakima does have a universal set that "clamps" onto your roof, but looks kinda janky and doesn't seem like it would do the body panels and its paint any favors.
