difference in s13 and S14 z32 conversion brake lines

[S14DriftR]

does anyone know the difference between a S13 Z32 brake line and a S14 one? Are they different lengths or do they have a different fitting going in to the hardline or something? I have S14 ones left from my last car and would like to use them on my S13 if possible.

very cool, I always thought they should be the same but was confused why places have seperate part numbers for them.
