the Classic square bar look from Thule did not fit for me... there may be a different dimensional cut or relief on that style bar than the aero (?) style bar shown here. I ran the bars back to the store, swapped them for a new set of the same width and ran into the same issue... no fit. I have that set now and thinking I might drill and then clean up the opening by 1/4" or so on each side (front and back) to get the longer length I want. I had the 53" bars so had them to compare side by side.
