From the link Kurt posted, this is an excerpt: "On the window sticker and on broadcast copy sheets, "1001AA" and "1001HA" have been observed as designating special paint cars. Note that all cars were painted, no Camaros were shipped from the assembly plant in primer".
In my documents under exterior paint codes, I have a line item that states: "Special and Prime" with production numbers as a total for both, so not so sure NO cars came from the factory, primed. Again just going by what GM docs state.
Same line item description for 1967, 1968 and 1969.
