I read about a man who worked for Chrysler in 1970 who ordered a gy8 71 440-6 pack challenger . non shaker auto car. he told a story of selling the car and in the trunk were records of production of some kind [not records of his car]as he worked for a section of Chrysler corp. that had the info! it was a quote to popular hot rodding about an article they did on my car.... he said that there were only 7 1971 gy8 -R/t- challengers built...
