Are the drivelines different for the autmatic and manual transmission modles of the first gen?

I know they are different in the second gen, but I wasnt sure about the first.

All North American spec Mazda rotary manual transmissions from 1974 through 1991 are the same length (~32") from the tip of the input shaft to the tip of the output shaft, with the possible exception of the 1974 RX-2, which may be around 40 mm shorter. Bell housing and input shaft were shortened for 1993-up models, and automatic transmissions with O/D.

All Mazda rotaries from US model year 1974 on are equipped with the same bolt pattern. All such transmissions can be bolted to all such engines. The large-clutch flywheels used on turbo models will prevent NA transmissions from being installed, but with no flywheel installed, an NA transmission will bolt up.

Now I could be reading you wrong... but the answer is they are different lengths.... right?

LOL, sorry. That was a copy and paste from a word document I create of RX-7 facts.

To answer the original question, the drivelines(driveshaft right?) are the same if the auto tranny does not have over drive. If the auto tranny has over drive, then the driveshaft will from the auto tranny will be shorter.
