Anyone know what this is?

Wasn't the Twister a low HP /economy version of the 340 Duster with similar graphics? Or for those that wanted the graphics but not the high insurance premium they were slapping on High performance cars?
Yes, Basically. 340 mirrors, shark tooth grille, and the ladder bar stripes on the hood. There are even differences between twisters.. you could get it with the 6 cyl, or 318 (this is a 318 car). Some twisters has the standard grille, some had shark tooth. It’s kind of like they stuck what they had on the shelf at the time on the cars, without much regard to all twisters being the same.
