The Canadian radio used in the AD trucks was the GM "Auto Radio Model 510". It was also used in some sedans including the Olds and the Pontiac. Here is a photo of it in a truck:

Now the dial glass is the correct one for the sedans as the radio was mounted in them with the dial at the bottom, or upside down as compared to the truck.

Here is a photo of a modern lookalike radio in the truck. Notice that the dial and knobs are the US style but the bezel is the Canadian version. This is an interesting combination.

This shop does immaculate restorations including some very high end classics.
