@46 Chevy truck.
What Otto said.
I'm not real familiar with the 46 beds, but I see on your pic, that your bed has tab sticking out each side for the tailgate chain hooks. I know on AD (47-55) trucks, the holes for the hooks are forward of the rear edge of the bedside.
What are the overall inside dimensions on your bed? A 46 Chevy bed would be 48.5" inside width and 78" inside length (front panel to tailgate.)
