Are these oddball emblems?

The posts on the "V EIGHT" emblems measures about 2 1/8". Somebody measured the "Formula S", and the posts measure about 1 1/2".

I kind of assumed that any emblem on this part of the car would use the same holes (D'Oh), but apparently, Plymouth decided to make different patterns for different emblems. I really don't want to drill into my new paint, so I guess the "V EIGHT" emblems are my choice by default.
