Is there a resource for, at the minimum, identifying prototype North American trucks?  Better would be drawings and the like for potentially modeling.

For my modeling era, I have a couple copies of the car builder's cyclopedia, '61 and '70 editions. Lots of drawings but hit or miss as to whether or not the specific truck / car / whatever that you are modeling have useful data or a potato-quality image.

I don't mean N scale, I mean prototype.

Doesn't that resource, at the minimum, help you identify prototype North American trucks?
