240Z up to January 1972 had the 5-speed A-type transmission
(3-piece housing/FS5C71A) in Europe. The same cars had the
vertical rear window heater lines. From later on they got the
B-type 5-speed transmission (2-piece/FS5C71B) and the horizontal
heater lines. Other useless trivia, they both had an overdrive 5:th
gear, servo synchro's and 3.90:1 final drive.
