Hi I was looking on ebay and saw an orange 69 z/28 car that had 2 stickers on the core support and one on the fan shroud. I know one on the core support would be the timing sticker.Is the other a high octane fuel sticker? the one on the fan shroud looks like a sticker for the antifreeze.None of the stickers are legible from the pics.If all these are correct, what is the proper placement of them.thanks
