Hi neilert,
Do you mean the small spigots that bolt to the rear wheel arches and fit inside the tonneau bar?
If so, I don't have photos, but simply made some up when I rebuilt my car. They were made from tube which fitted snugly inside the tonneau tube and was then flattened and bent to suit the rear wheel arch contours at the other end. They fit into the bar by about an inch and are totally about 2 inches long.
My car is away at the moment, but can take some photos when it returns if you require?
Cheers,
Mac.
