I'm thinking they had a black and white decal, about 4-5 inches long, round on both ends and flat on top and bottom, about 1 1/2 inches high top to bottom. As I recall, there is a yellow Yenko Chevelle from South Bend that still has the original sticker on the rear bumper. It's been to the SYC reunions too, so you might find some pictures of that car and the S.B. decal to give you an idea what you are looking for.
