Thanks tca and ERM636 - I was hoping someone had a low mileaged / know no wrecks car to measure. I'm repainting my project - still going back and forth on 5.0 emblems / no emblems / could go 5.8 (installing a 351w) but those are - I don't know - odd to me - or small pony emblems (from 03/04 V-6)...
