I have a z32 na vlsd pumpkin with abs and with the 5 star outputs.
I know this z32 na abs pumkin wont fit into a s13 because of the abs sensor thats at the front of the z32 na carier, a abs drive shaft is shorter and wont fit because my s13 is non abs.
So what I plan to do is swap the z32 internals ino the open diff carrier.
Ive noticed and also heard that u swap the open diff ring gear replacing the z32 diff ring gear.
thats the only thing that I noticed because on both ring gears it says 49:12 same, so that seems that they will swap without problems.
any other problems that I may encounter?
And also after removing the bearing caps when removing the diff, whats the process of popping out the diff, because I noticed its pretty wedged in there, Im having a bit of trouble removing it.

The Z32NA pumpkin will bolt up, but it has to have the 240sx's diff cover swapped on it. The output shafts will work, but they cannot be mated to the 240sx axles (Z32 uses a 5 star with 5 bolts, 240sx uses a 3 star with 2 bolts on each star-point) and you cannot use the Z32NA axles...they are too long. Therefore you need the five bolt axles from a JDM180sx or J30....or you can purchase the 3 star VLSD output shafts from somewhere and mate them to your 240sx's axles.
www.car-parts.com will have the J30 axles, I belive you will need pre 95 axles.
