The eighteen points mirrorcell.
(the bolts have to be cut off of course)

Frontal view of the cell in the mirrorbox, with a "traditional" safety belt sling. After having used this one a couple of times I made a double sling from bicycle brake cable because of the stretching of the safety belt. There's a special page about how I did it.

Back view with the mirror mounted in its cell. The fan is attached to the tailgate with velcro strips.
