Only one I could find. Maybe find a 1971 Plymouth or Dodge brochure?
This Duster supposedly has the Twister trim package, new for 1971. It lands between the base Duster and the Duster 340 and essentially was a Duster with more standard features, such as Rallye wheels, racing mirrors, side and lower deck stripes, a flat black hood with hood scoops, bucket seats, and a unique grille all as standard equipment. The appearance package was topped off by a little cartoon tornado with an eyes logo on the back panel near the taillights. With that said, I don’t think this is actually a Duster Twister, because most of those items are not present. Can any of you Mopar fans confirm?

Even so, the body is in pretty good shape. The seller mentions that the floor and door jambs have been repainted, but the rest of the paint is original. There is some
rust forming in a couple of places around the rear wheel wells, however. The seller says he installed a new
windshield right before listing the car, and even though you’ll notice in the photos that the windshield wiper arms and some window trim aren’t installed, they are fortunately included with the car.

The interior has recently been completely replaced, including headliner,
seat covers,
door panels, package tray, dash cover, and carpet. There was also a
new floor pan put in, which was professionally painted afterward. The interior looks great with the only exception being some chipped wood applique around the gauge cluster.

The drivetrain is Mopar’s venerable 225 cubic-inch slant-six paired to a 3-speed floor-mounted manual transmission, which puts out around 145 hp. The seller says the engine was rebuilt around 2006 before it was parked and stored in a garage. It now has a new gas tank and a rebuilt single-barrel Holley carburetor, and we are told it “purrs like a kitten” with no smoking or leaks anywhere. This car is a solid turn-key opportunity for someone. Would you continue to drive it as-is, or begin upgrades to make it feel more like a muscle car?
