ISUZU Used! Genuine 117 Coupe rear bumper

This is a used genuine rear bumper. It is said to be from a 117 Coupe (early model, round headlights), but further details are unknown. It is a genuine rear bumper made of steel with a chrome/black finish. There is severe rust on the underside of the bumper, and there are many scratches and dirt overall, so it does not look very good. How about using it for repair or modification? Please check the condition before purchasing.
