Not really that familiar with the truck caps in later years but what threw me was the raised areas on the outer edge of these caps. They look identical to the 57-60 caps except no small bowties. The non-cone shaped centers with the bowtie made me wonder if the caps might have been from a much bigger truck. The one inch or so vertical edge at the rim of the cap made me wonder also. Definitely not described correctly.
Thanks for the observations and comments.
