Differences in Formula S Emblems

This got me from earlier today. I knew there was a difference in the S Side Emblem and a 69 Rear Trim Panel. There was a sale post but I didn't want to post on the sale thread.
But I didn't know there are curved 65 emblems with vertical mount pins and then there is a flatter emblem 66-68? It has horizontal mount pins.
First I have heard about this.
Am I saying this correct? 65 Emblem and then 66-68 side Emblems?
