thule fairing for a ski & snowboard carrier

[FLIPSCOUT]

I have a OEM racks with the ski & snowboard carriers, and I was wondering where I can start to look or what fairing is the correct one for my carrier?

Go to your nearest racknroad buddy, best advice I can give, I've seen people use Thule fairings, but I don't know if they rigged it on or not
