Placement of Demon insignia on fender?

I am planning to put new insignia on a 72 Demon with tape stripes. The problem is that neither the parts manual nor the body repair manual are adequately specific about where it goes. There aren't many Demons, let alone those with decal insignia, appearing on the show field in this part of the world. The last show I went to, I got lucky and snapped a photo of a Demon metal logo in what I believe is the correct location on the right front fender. Unfortunately, I did not have a way to measure the placement of the insignia.

I would appreciate an accurate measurement from the base to the tip of the middle tine of the pitchfork. I'm looking for outer chrome edge to outer chrome edge, accurate to 1/32". (Dimension z on the attached photo)

Using geometry, I can determine dimensions x and y allowing me to properly place the decal. In advance, thanks for any help you can provide.
