The helmet got cracked between the brow line and the first vent, then another crack between the first and second vents.
The visor was useless to me since it extended down into my field of vision, but was thankfully easily removable.
Sadly, that also made the mirror useless, since it was attached to the visor, so I bought a 3rd-party mirror and adapted it.
I think you may need to consider getting a new helmet to attach the mirror to.
Or perhaps you think that it saved you worse damage then, so will do so again!
