Fairing for roof rack

[fjmax]

is there a fairing or wind dam that can be installed on the factory rack. i know that you can get one from toyota with the lights in it, but i'm looking for just a regular one. it doesn't look like the yakima or thule ones would work unless you install one of their cross bars as well. but i've noticed that there seem to be four screw points where you could easily mount one if you can find one.

i actually got the roof rack installed after the fact and quickly noticed how much noice it makes. so if anyone knows where i could get a fairing i'd appreciate it.

thanks -
