i.e. if your s13 had an open diff and no abs, you will not be able to swap the s15 ring and pinion because the shaft of the pinion gear is much longer than the one for the s13 open diff.

False. The pinion gears are the same length no matter if its ABS or Non-ABS. I have taken apart over 20 different S13 / S14 / S15 differentials so I know this to be a 100% fact. What changes in length is the pinion flange and the pumpkin casting itself. What will happen is the ABS models the pinion gear will appear more sunk in while the Non-ABS protrudes more.
