68 camaro emission decal

[68z28kk]

I have been working on trying to document a 68 big block coupe that I bought about 15 years ago. It has some performance pieces that should help in determining if it is a special car. Yesterday while working on it I was looking over the front end parts and noticed what looked like a painted over emission decal on the drivers side of the core support. It had been painted over in a gray enamel but I could see the outline of what was left (about 80%)of the decal through the paint. What I need is a clear picture of an original 68 L78 decal to compare with mine. On the lower edge of my decal the paint has chipped enough that I can see parts of a few numbers that I could compare to an original and see if I have a possible match before I go to far and lose the information. The L34 decal may be helpful also in case I've set my sights a little to high. As I progress in my effort I will be wanting to post some pictures of some of the special pieces in hopes that someone can help point to a specific builder. The car has survived pretty well and shows signs that it was a POWERHOUSE at one time. I have looked but have only found Z28 decals in any reference material.
