Why is one drive shaft slightly longer than the other?
Pictured are 2 drive shafts exactly aligned at the pinion gear end. One is noticeably longer than the other. Which one is right for a 1925 motor with a 1926-27 differential? The longer one came off of my Touring parts salad car of unknown history when I first took it a part and had all kinds of bizarre hacks on it to make it work. The second one came from a trusted source.

Re: Why is one drive shaft slightly longer than the other?
Years ago John Regan was disgusted with the drive shafts being sold at the time, and started supplying new ones correctly made to the Ford prints. If you're a better Google searcher than I am you might find his forum posts explaining the difference. The parts book shows the same DS for all years 1911-1927. Ditto Lang's catalogue.
The inevitable often happens.

Ignacio, The shorter trusted one looks more correct. Check your U joint on the shafts to see if the U joint pin hole matches up. I think the longer shaft will stick out into the joint area of the U joint Look on the shafts for Ford logo on the U joint area flats.

Bingo the U-joint did not fit on the end of the longer shaft from an unknown source at all. It fit perfectly on the shorter one from a known source.
