i am hopefully going to be buying a 1971 challenger r/t with the shaker option tomorrow. 383/4speed. 3.91 suregrip. plum crazy with white stripes, vinyl top, and interior. it is a rough project missing the drivetrain, but the price is right. once the deal is done, and the title is in my name, i will post the vin. it is an early production model; september 1970 as far as i can tell.
