Yes, but .....
a-bodies handled axle ratios differently and AARs - T/As were 3.55s STANDARD & 3.91s no-charge (NO axle package). "NORMAL" '70 'Cudas & Challenger R/Ts had 3.23s STANDARD - all of the higher numerical axle ratios (3.54s, 3.55s, 3.91s, 4.10s) were only available in Axle Packages" that will be on the fender tag. 2.76s were RARE but available on '70 'Cudas & Challenger R/Ts, but not available in a '69 Road Runners.
