There are some incredible deals to be had from Chinese ebayers. However, you take your chances. I bought a beautiful chrome front master cylinder for $25 to my door. Arrived super quick also. I'ts sitting unused because the tapped thread for the banjo bold is just too loose. The banjo bolt isn't tight until the last turn. It would probably work, but I would always be worried about it leaking or just coming off spilling brake fluid all over my new paint.
