Yep, Jeff (Lextech) is correct. there is a 3100 emblem that goes there but it shows to be a 51/52 item and not a 53 item.

The proper 53 emblem shows to be this one which also fits 54.

I went out and looked at my spare hoods and one of them has the Chevrolet emblem with the small 3100 below it in proper position for the small holes in your hood.
