73 barracuda 340 727 driveshaft question.

[Flathead31coupe]

I was changing universal joints and noticed that the slip yoke was on the bigger end of the drive shaft instead of the tapered end like i am used to seeing.. Just so happen was watching graveyard cars and noticed a barracuda.With the drive shaft the same way, the slip yoke was on the bigger end and not the tapered.end. thoughts?

wait, are you saying the drive shaft varies in diameter across it's length? I always thought this was a uniform diameter on my 1970 shaft. The only clue to it's orientation I can recall, is a tiny counter-weight welded to the tube near the slip yoke at the transmission end.
