Plymouth Duster 340
The 1970 Duster was available in two models — the standard Duster and a performance-oriented Duster 340.
At midyear, a Gold Duster trim package was added. The Gold Duster package came with either the 225 Slant Six or the 318 V8. It also came with special "Gold Duster" badging, gold stripes on the sides and rear, wall-to-wall carpeting, pleated, all-vinyl seats, whitewalls, wheel covers, a deluxe insulation package, and a canopy vinyl roof. The Gold Duster was offered through 1975.
