55 Chevy pickup side air vent door

[wilberweb]

Hi, Guys does any one know where I can get the side vent boxes for a 55 Chevy 3100, I looked in my after market parts books, and can't seem to locate any, and no reference on line for this kind of fix, or any kind of patch panel for this application as well.
Has any one replaced the vent door and metal around the door mine is in bad shape its rusted out as you can see.
Any help would be great.
