Here are all four stickers combined. There is one missing that I wish I had filed away. Kurt posted it off of eBay but has since expired. I would like to compare it to your original. Anyway, your sticker is far more accurate than that other one which lacks the proper font, spacing, punctuation, etc.
The corners as you say are a hard call. Although I think you might be exaggerating them somewhat (just my 1 cent
). No telling what 40+ years of heat/elements can do to a sticker.
Can you or anyone else tell me what “CU”, “CV”, & “CO” stand for and why so many variations? And, which one of these would be correct for a '69 L48, 12A build?
