1968 Dodge Coronet 440 wagon 318 / automatic

As far as I know you can on the 1968 cars, at least what was originally installed.
I have checked 2 other 1968 cars that I have owned recently (1968 Plymouth GTX 440 HP, 4-speed, 3.54:1 Dana 60 & 1968 Dodge Coronet coupe: slant six, manual shift on the column, 3.21:1 small rear axle) and so far the 1968 fender tag decoder has been accurate with what axle & raito those cars came with.
