Newbie here with a 1990 300LE Classic Airstream motor coach. Had a contretemps with an immovable object while backing up. The aluminum bumper is pretzeled and what would be called the right rear quarter panel on a car (the plastic piece with the side marker light in it) is toast.
I think I can straighten the bumper, but I'll need to replace the plastic piece. Any advice on sourcing one?
