I'm not sure how rare the color was but it was also used on GTO's and Lemans, "Antique Gold Poly, PPG #2082" was also used on the wheels in 1969. There was also "April Gold Poly PPG#22942" used in 1968, and "Coronado Gold Poly PPG# 22728" that was used in 1967, spring color only, but rolled into 1968.
And for all you "GREEN GUYS" it is actually "VERDORO GREEN POLY" PPG# 43745, 1967 spring color, also used in 1968. I'm not even going to get into the REDS...unless you want me to
