The 1.06 is inches. Use a limp tape measure and wrap in along the curve from the lower edge.
I put 400 emblems on my 326 hood. The holes are different and it's tricky. I made cardboard 400 emblems by tracing the emblems and cutting them out. Then I positioned them strategically to cover the 326 emblem holes, then marked the new hole location and drilled. Came out great, except for the fact that 400 emblems don't belong on a flat hood.
