I am looking for A Thule fit kit 1566 for a 2010, also has anyone ever used a different fit kit since they discontinued that one?
I couldn't source a 1566 kit for you, but possibly found a Thule Kit that might be compatible. You will have to do your own research further though if its a possible solution. Click Here for the PDF of the 145001 Thule Kit Click here for Thule Website Kit's link All the research I could do this morning for you. You will definitely have to do more to be 100% sure it works.
