Fuzzy,
A fairing on the ol' roof rack would be great, but I don't think that Yakima sells the horizontal mounts for our cross bars anymore.  I'm sure I might be able to fabricate something out of metal or plastic strapping if I had to.  Are you going to go to Moab so I can get a closer look at your set up?
