Posting here before it goes on CL this weekend.
I have a pair of Thule aero bars (48") with a set of (i believe) Yakima towers. Towers are clamp style for vehicles with raised side rails. Fit perfect on wifes Sorento. I have a whole different set up im using.
Has no locks though they can be added. Has rubber inserts in crossbar groove to prevent whistle.
I can send pictures if interested.
Email is best.
