I was checking the particulars of salvage/reconstructed titles for automobiles in New Jersey when I found this under the "Special Vehicles" section

Titles for the special vehicles listed below are only issued by mail from the MVC Central Office in Trenton:

- Reconstructed vehicles-dune buggies, kit cars, etc.
- Glider kits
- Vehicles with missing VINs
- Vehicles registered to the military

Glider kits?
