Three parts to mount a digital rear view mirror on the factory metal base on the windscreen.

It uses the factory metal clip which needs to be redrilled for the self taping screw or whichever screw you want to use.

M3 Screw and Nut used on the swivel part of the mount.

Normally those digital Mirrors are mounted via a rubber band onto the stock mirror. As the Ducato/Boxer/Jumper sometimes don t come with one, you can cut the ears of the rubber clip and glue it inside of the new mount. They are sliding down, so still fully functional, see attached pictures.

Newest style of mirror mount. Older Ducato/Boxer/Jumper have a slide on base for the rearview mirror, newer ones, like this have a clip on base.
