In that case you'll need to get the form Report of Lost or Stolen Motor Vehicle Items (MV-78B) from a police agency.
I thought so. And if they were not just lost, but stolen?
You'll have to also get form MV-78B if your items were lost because of a crime. Your items will be replaced at no fee if form MV-78B shows the items were lost because of a crime.
Is it possible to do applications by mail?
