Order anything EVO-R from -
Motorsport! 370Z Parts Home - The Z Store, Nissan-Datsun 240Z-260Z-280Z-280ZX-300ZX(Z31/Z32)-350Z-370Z Parts, instead of directly from him (even though I never had any issues with the 2 direct purchases I made).
They will only sell you whats in stock, ship on time, back the purchase and exchange or allow returns if you are not happy with the quality.
