My JDM import documents got lost/stolen

like the title says my jdm import documents got lost/stolen. I believe what happened was i put my documents on top of my car(because i leave my school bag in my regular car) to go pick up the imported car and hopped in one of my friends cars forgetting it was there.(i was street parked and i had school so i was rushing) i checked everywhere for the last 8 hours (trashcans, couches, streets, asked neighbors). I lost all the original documents including surrendered bill of lading, export certificates, and documents with my ssn, phone number, email, and address written. I am wondering if i can still get the car registered and what steps I should take. i tried filing a police report about the lost stuff but they just said to call dmv and ssn tomorrow. Im worried about both the information being used for identity theft and potentially wasting 7-9k on a car id only be able to use for a month legally. any information would be helpful.
