A3 thule rack on factory rails
 

Does any one have a Thule rack fitted to the A3 factory rails ?

Seems that there has not been anyone asking (or info posted recently) about Thule versions that fit on the A3 factory roof rails. There were posts in 2006 about people getting European Thule towers that fit on the factory rails. Has anyone figured out if there is a US version. If there is a fit, does it allow opening of the open sky?
Thanks in advance for any posts/info
