PartsRack has sold a few.
We take em in TRADE for the **** MGW cap.
They dont fit down inside the fuel filler nacelle like GTS. They sit atop the DRILLED fender, requireing a custom gasket, and giving it a strange, un-aero look that some call the "Viper Wart"
The lower profile of the MGW cap would look better than OE, but still are an awkward fit in my opinion
