GOLD DUSTER first year??

Looking further, the initial Gold Duster package was released as shown in the foregoing ads in mid 1970 to celebrate the sales of 100000 Dusters. The largely appearance based package included Gold Duster decals, stripes, dual horns, whitewall tires, drip rail moldings, and bucket seats. The package was carried over into 1971. It seems it was a less formal package without a separate sales code like the code A64 used in 1972-1975 and did not include the canopy vinyl roof released in 1972.

Found online is the following picture of a 1970 Gold Duster.
