That is not the sticker I have found used on unrestored cars built slightly later than your car so I would guess the other design would cover your cars time period.
Have a Jan 15 1970 still using the C9xx prefix -B - 2 version
As you can see in the picture below the date stamp was added later (not printed with the sticker) so the font, coloring and look are different unlike the reproduction you show in your post. Before someone else mentions it yes some PO has been in there were a black rattle can painting all the hardware and "freshening up"
things though the sticker appears original
