YENKO TUNED decal?

[bkhpah]

There are at least two types of YENKO TUNED decals. One with all block letters which I beleive is a early example and one with the Yenko crest and Canonsburg PA. The paperwork with my Yenko built race engine that was installed in my Yenko Camaro has notations about Yenko Dyno tuning but no decal on the car. I know that the Yenko tuned decals are available but have never seen a 100% certain installed at Yenko decal. People seem to add them because they are cool more than accurate.
