82 D150 cargo light

My truck has a place where the cargo light should be, but no light. I grabbed one off a 90 D150 at the local PNP but it's entirely different. The spacing for the mounting screws is 5-3/8" CTC and there are two wires coming off the switch to the light. I'm guessing it has two bulbs? Here is a photo of the cab, sans light. Does anyone have this light, or know where I can get one? Heck I'd be happy just to see a photo of what I need so I could narrow down the search....
