S13 output shafts

[matt0481]

I'm new at the performance parts thing here. Why can't the output shafts from a S13 non-VLSD diff. work in a '90 Z32 NA VLSD? IS it the shaft diameter, splines, or length? The pictures I see in the swap writeups appear to show no differance other than the axle flange. Thanks for the help.

its very different
size, splines, etc
if you look at them, you'll see
even w/in s13 the open diff each side is different. then more differences w/ the vlsd too if u compare that w/ the open.

Where can you find the output shafts and for how much?
Thanks!!
