Yes that's right,
Bryan, somehow I think we're saying the same thing differently and thus the confusion.
I'm using the blinkers that go on the rail, thus the stoppers L & R and the stems as per the schematic, I'm in the process of buying the parts.
I still don't know how to mount the little black indicator mounts, I can see them on the blinker schematic, but not where they mount? And I haven't seen a photo from anyone where and how they bolt onto the frame.
