I have two different sets for sale, each set is $150.00
* One set is for small car, I had it on Mazda Protege
* One set is for SUV or Mini Van with side rails on roof. The clamps mount around (over) side rails. I had mine mounted on Venture Mini Van.
Comes with rails, 48 inch wide, mounting clamps including all 4 locks. All in good shape.
