zx9r rear indicators

So, after much thought and deliberation, Ive finally decided whats happening wth the three of my current bikes.
Im keeping the zx9r and Im going to try and find an akrapovic system for it.
But in the meantime, I cannot figure out how to secure the rear indicators in their slots.
They have the long bolt on them and a nut that goes at the end, but when I get them in the slot
on the fender, they still dont stay in. Am I missing a bracket that goes on the inside of the fender?
Apologies for bad wording and lack of photos

Like this?

I think a DIY section on this forum would be a great idea with a video.
Probably even better across the rest of the board.

Those with the time/ decent camera, and the bike in question can post A video via you tube of how something can be done.
Visual means would be an addition to reading help.

What do you reckon ?
