You may want to look into California law before removing the VIN. In SD it is a felony to possess a vehicle with an altered VIN.
In Idaho you can drag an obviously stolen chassis out of the forest to clean it up. Give the police gps coordinates, description of how and where you found it, 2 months later drag it home and they still wont come look at the vin on it.
I finally sent it to a guy out of state that needed a bulkhead just to get it out of my yard.
I would say if you salvaged the sled sans the vin number, to retunnel it and then let em know you had done it.
But then of course that would be illegal.
