Believe it or not I found this page along with other year Camaro info buried in the 1957 Chevrolet GM Heritage Kit at this link:
https://www.gmheritagecenter.com/docs/gm-heritage-archive/vehicle-information-kits/Chevrolet/1957-Chevrolet.pdf
See pages 86-103 for oddities that don't belong in this kit
