Greg,
I'd suggest that you look at photos of the 2 914-8s & the pre-production promo 914-6s when Porsche did put badges on the 914s to eyeball the proper placement which they intended for it. You can use a known part like the headlight eyebrow or lid or the badge itself to "measure" the gap between the bottom point of the badge to front edge of the hood/deck-lid, then use math & a ruler on that part to come up with the actual gap measurement.
IIRC that thread was using the 911/912 recco'd placement of 8" back from the front edge of the hood, but it always looked to me that Porsche probably used 8" or so back
from the front edge of the front bumper top pad instead, in order for it to look right.
If you google for images or look on the posts on here, you'll see that folks put them everywhere from a couple-a-three inches from the front edge of the hood panel, to mid-way of the headlight doors/eyebrows, to way up even with the top of the headlight doors hinge-point.
IMHO it looks best closer to the hood front edge (just above where the frame on the underside ends) - along the lines of what the factory did on the ones noted above.
It sounds from your recent posts, that you're making good progress for the upcoming 2017 Parade in Spokane!
Good Luck & Happy Holidays!
Tom
