i think only 4600 r/t challengers h/ts were made in 71 . i had given him a choice between my two challenger r/ts i had at this time keep n da r/t with the carrillo rod 440 6pck in it , funny thing i like cuda's better , bought this challenger r/t for the motor trans combo for my 65 sat comdo , there is a story on that car . my room mate in the mid eighties bought and sold a few challengers , even cut three , one 70 r/t , 71 and a 72 . both wrecked hard , today they would have save them both . but i was after there parts , the 70 r/t orange wht top n interior , 340 4spd . guy was horsing around in a parking lot got chanced by the rent-a-cop , went to leave through the wrong driveway . well it had a steel post sticking up bumper high , he don't even see it . bent the car right down the middle , sucked the front fenders under the hood , broke the crank off , blow up the bell housing , broke the shifter mount bracket , broke the input bearing and clutch release bearing colar , stuff the drive line into the trans , well yes that car got bent up the middle hard , bent the trans tunnel big time too . it was not bad rust wish , would have made a race car from the shell without a floor , room was short then . it had to go , there were more to buy . we even traded a 72 rally one to are maid , that cleaned up the castle for us . we always need more time to party , lol . send lots of money on them time though .
