ok thanks, I now see what you mean by deflector...
I thought you meant that your basket was attached to a Thule set of rails fixed to the VX, but may be your Yakima basket is fixed to a Yakima set of bars & fixings? What I was after was the reference of the discontinued Thule roof rack and fittings they used to make for the VX to see if that old reference could be cross checked with existing products....
