My info says they did indeed make more 4 speed Dart Sport 360's than autos, but only by a little. Total Dart Sport 360 was 2,348. Weird thing is the book has a line for Dart Sport 360 that says 3,314 total produced, so not sure what is going on, but the 2,348 listed does match the total number of autos and 4 speeds. Maybe the total was 3,314 and there were 966 built with 3 speeds?
The numbers for the Duster of the same year list total production of 277,409 which, of those there were 3,879 Duster 360s broken into 318 3 speed, 586 4 speed and 2,975 autos.
Best guess, Galen's book has has an error and there were 3,314 total Dart Sport 360's build and the break down is 966 3 speed, 1,186 4 speed and 1,162 auto. That makes sense with the numbers in his book, but it's just a guess.
