You may still be able to claim all of that if they total it. It's been bought and paid for, and it's all vehicle specific parts, and still a loss on your part in the vehicle. Won't hurt to tell them about it, and let them know its all non-returnable, and show receipts. Play the game.
The difference between stupidity and ignorance. Ignorance is doing something wrong and not knowing better. Stupidity is knowing better, but doing it anyway. Don't be stupid!
