The picture shown in the link is not an X6, but you'll see how they fit into the channel rather than the stick-on type. There shouldn't be any binding or rubbing, and in my experience, the fit was quite good and didn't interfere with window operation. The f/r set is $95. These ship from Downers Grove, IL, so they shouldn't take long to arrive.
