Found 1971 Duster twister Build sheet and fender Tag

Let me start from the beginning. I sold this car 22 years ago. The guy that bought it, I delivered the car for him local(real nice car to start with). He was suppose to come back and get the rest of the parts and paper work. He never came back. I talked to him for a few years telling him I still have the stuff. As time went on I never heard from him again. I thought maybe It was coming to be a race car and did not care about that stuff. Well yesterday talking to a local guy and he is describing this Duster he just got, I said your car sounds like my old car, he said this guy had it for ever and he did not think so. I gave him the vin. He said holy cow I cannot believe it that’s the car. Then I told him I have the fender tag, build sheet, and original title. That blew is mind! SO COOL!
