(Yet another) roof rack question

[thedutchguy]

Do what I did : go to the nearest thule dealer.
They have all the info you need, take measurements and order one for you.
If it doesn't fit, you don't have to buy it.
In my case it fitted perfectly,I'll try to recover the numbers of my rack.
But since there are none on the rack itsself, it may take a while.

On this note, does anyone know which Thule or Yakima mounts fit the extra-wide VX cross bars?

I usually use my Yakima carbo box, but I'd like to put a powderhound ski rack on it since it woudl be more compact, and as noted above, they are cheap and plentiful on eBay.
