1971 Challenger A21 & A22 option packages with paint availablity and information at http://www.hamtramck-historical.com/images/PIBs/1971/71D%20pib%203%20p1.jpg



Barry,

This would imply that non-R/T Challengers would get an A21 or A22 code on the fender tag. Where as R/T Challengers have an M71 or M73 code on the build sheet only.
