In answer to your specific question: 41 1/2" from center of the U to center of the U, for both the auto and manual.

Re: Driveshaft measurements

The same length as 84-92 third gen driveshafts with a 700R4. 82-83 may have the 200c which uses a different length.

You won't find a driveshaft in any other car the proper length for a third gen except maybe from a fourth gen. If you want to get one custom built, the measurement is from the center of the u-joint on the diff to the center of the u-joint on the tranny yoke but the tranny yoke must be installed into the transmission then pulled back out 1" before taking the measurement.
