Rear end swap

Alright so, over the winter I’m planning on doing a lot of work to my S12, one of the projects includes finding a way to fit a goddamn LSD in it, the welded diff is annoying as fuck. I’ve tried just straight swapping a s13 VLSD into it but it doesn’t fit. Does anyone know if it would be possible to swap in an s13/14 rear end? (Axles, half shafts…etc etc)
