Etched glass window decals

[TWISTER]

I saw awhile back an etched glass window sticker that was made of the buick tri shield and cant seem to find one now. The decal was about 6" in diameter and was of the buick tri shield. I think Roberta from the Chicago chapter may have one on the back of her GN. I had found it on ebay but now I need it for a stereo mirror and cant find one. Any help would be appreciated. Even the Turbo 6 could work but it has to be the etched glass look.TIA
