I got a set of speed pro plasma molys, lost the directions, and now Im not sure which ring is for the top. I cant find any pics or any posts to help. one set are all black with a white mark on the face and are chamfered. the other set has a white mark on the face with a dot on the ring, a red mark on the face, a shiny face, and no chamfer. 1st motor build. HELP. thanks j
