Mercedes Vito Viano sun visor coupling support

Left side sun visor coupling. The visor cables have to be cut (and optionally reattached, I didn't, find that light useless).

Room to improve:

- it fits, but I think one screw should be slightly offset - but fits with no great effort.
- there's a recess in the sun visor I'm ignoring, and would be useful for turning it 90º left.

The coupling for the other side (copilot in my country) is just a mirror image. In the proper axis :-)
