It's also interesting to note the slight variances I see sometimes between an original sticker and a repro sticker. For instance, the original window stickers (for Firebirds at least) do not use a thousands notation, so "4,963.25" appears as "4963.25". But on some GTO window stickers Pontiac used the thousands notation. Perhaps they omitted the thousands comma on the Firebird window stickers to save space due to the smaller form, I'm not sure.
Also, some of the original window stickers have the VIN prefix and serial number in the same font, while others have the last 6 digits in a completely different font, crooked, etc., like what was shown above. Doesn't seem to matter whether it was Lordstown or Van Nuys, I've found examples from each plant. So I'm not sure why there were such discrepancies.
One of the hardest things to duplicate though is the comma used in the dealer's name, city, etc. The comma used up there is always very thick, and is about half the height of the rest of the letters.
