At a recent Old Iron meet in the local park, I saw a 31 Chev coup with the curved front horns like I have on my frame with the "C inside Diamond" brackets as mentioned in my original post. As there had been recent rain and the ground was soggy, I didn't feel too inclined to lay down and look under the body for additional similarities. The owner was not present and I as unable to get further information and didn't think to take a picture.
Can anyone confirm or refute that -C inside Diamond- logo as related to Chev? I have tried to find info related to frame dimensions and profiles but didn't find anything for this era. Nor did I ever find that logo - or anyone familiar with it!
