1972 Demon 340 Fender Emblems

I am looking for the correct measurements to mount the "Demon 340" emblems on my '72 Demon fenders. I had to replace my fenders and now I want to drill the holes for the emblems. I can measure for the "Demon" emblem from my old fenders, so really I only would need measurements for the "340" emblem. If anyone could measure for me from there car or have a fender with holes that they could measure it would be greatly appreciated. Any pics. you might have to would be great! Thanks.

Here the emblems I have.
