S13 open diff into a 95 vlsd s14 - what's needed?

So I have a 95 s14 with vlsd, got a s13 open diff laying around, assume it’s welded, can I just change the rear cover and swap it in? I heard something about axle stubs, someone please shed some light on this please, thanks.

I know this is a buy/sell/joke forum but someone must know their shit
