J30 vlsd swap

[240s13silvia]

So ive purchased an abs j30 vlsd for my s13. I swapped just the differential itself not the entire housing and everything due to my purchasing a nice one peice driveshaft for a non abs car earlier. So ive got backlash within spec and new side bearings installed and im having issues on fitment of the stub shafts.so has anyone else done this before? And which shaft did you use. the nissan shafts or the infiniti shafts. I currently have the infiniti shafts installed but one sticks out farther than normal and the other one goes in to far. Let me know what you guys think.thanks a lot
