I had to purchase from dealer, I think it was approx $67.00 USD. I usually hunt Craigslist for this kind of stuff. It worked great for my other Thule rack. I bent one of the feet. Found set of four on Craigs for $20.00. Now I have plenty of spare parts. I pulled the 2167 instructions from the Thule website. I shows that the bars should be mounted 24" apart. Don't know if the ski box will work with the bars that close, we'll see.
