[S1013]

I am in the bodywork phase of an ERA slabside. While the exact measurements for mounting the side emblems for the 427 car is quite easy to locate, I am having problems determining exactly where to drill the holes for the 289. I do not have easy access to an original to measure. Looking at all the photos I can find it appears to be about 1/2 inch higher than the side vent and the back side about lines up with the hood handle. Greatly appreciated if anyone has some real measurements.
