Hi guys, i hate to be a pain with such a non knowledge question, but i'm new to mopars and muscle cars in general and i bought a 71 rt challenger. It is white with the black stripe package, was a 383 magnum now with a 72 440 in it, 727 trans with column shift, sure grip rear i think, not sure of ratio, black rear spoiler, factory hood pins, magnum 500 wheels with matching spare etc, tan interior with full guage package. I thought this might be somewhat rare because of the column shift and white hood with a small rt on it not outlined in black. The car has be owned by the same old lady since 73. Is it a fairly rare car the way it is? Once again, sorry to be a pain.
