I have a lightly used set of roof rail cross bars for the A6 Avant wagon. These are an original OEM part from Audi (part number 4F9 071 151 666) and fit the model years 2005 to 2011 (according to a quick google search), may be modified to fit other models with preexisting roof rails. The sale will come with a key that unlocks all for locks on the clamps. The item is near 95051 and i'll ship.

send me a PM if interested. thanks :-)
