magnum - maybe someone with a bare bubble will chime in. Sorry, but I'm going to pass on pulling the emblems to measure the hole. The original studs are somewhat prone to breaking and the speed nuts sometimes take a little material each time they go on and off. I think your first picture looks pretty similar to my first picture. The D/S emblem seems to angle up a little more. It's probably exaggerated by the large 440 sixpack emblem. Maybe someone will post a pick of the 426 Hemi emblem which is also kind of large. I'm pretty sure all the holes/studs were the same regardless of emblem.
