Evo R Rock Rail Cargo Eyes

[dbrock]

I am looking for some cargo tie down eyes or posts that I can slot into the rails for my Evo R Rock and Roll bed. I need to secure cargo on the floor in front of the bed and the rails are perfectly placed, however I need to lock some eyes or posts into the rails at various points so that I can stop my cargo sliding around. Does anyone know where I can buy such fixing points and whether the Evo R rails are bespoke or generic?
