you need the rear door cladding, I have it!!! just make offer and we can work something out. New it costs over $300 from Isuzu.
sorry to here of your misfortune. It reminds me of when I was helping a friend move his car with a car dolly where you drive on and strap just the front wheels down. Well, he decided, that when I was getting something to drink and my VX was unattended, to undo my hitch receiver with the car attached and push the car off the dolly with the chains still attached.
The car made the dolly launch forward into, you guessed it, my rear door. Surprisingly it just dent in the spot where the license plate goes and you can't notice.
