Let's remember that illustrations in shop and parts manuals were prepared well in advance of any actual production and were often based on display, testbed or prototype engines and vehicles. While they and the actual parts manual listings may be about all we have to go on, they are not necessarily indicative of actual production details in such matters. Of the two, parts listing are more likely to have been updated or have had corrections made. I doubt they ever reissued a shop manual just to update an illustration for something as minor as a hose clamp.

Not that this helps answer the question; the best information comes from original unmolested vehicles, which as far as things like radiator hoses and clamps goes, will be difficult to come by.

If I were in a judging situation, I'd probably let parts listing information override shop manual illustrations in cases where they gave conflicting information.
