68 barracuda trunk decal

newbie here.

I recently bought a 68 Barracuda and was wondering about these reflective decals... my car was repainted and doesn't currently have the decal. can you tell me, was this decal applied to all of the gen 2 barracudas, or just certain years and packages? I've been digging around and can't find any info. I'm also looking for information on the "horizontal accent stripe", if you know anything about that.

thanks.
