I have a 202 NX300H with the side rails. I already own a Thule luggage box from when I had my Ford Fusion. I want to reuse the box on my Lexus. Does anyone know if the Lexus cross bars will work with a Thule rack? I got an estimate for cross bars from where I bought my box and it is twice what the Lexus cross bars cost. I want to make sure they will work before I buy the ones from Lexus.
