Nismo 2 way question

[nfakbc]

Yes I have already searched but found nothing that I am looking for. My question first is I purchased a used nismo 2 way but am unsure if its for a open diff or a vlsd. What should I look for as to what it is for? My 2nd question is I'm thinking about rebuilding it before use. Can you get the rebuild kit at the dealership or is there somewhere better to get it.
Thanks in advance for any answers.

are there any imprinted numbers or letters on it that you could use to search with?

First of all try it out with your open diff pumpkin. I'm pretty sure it will fit, because i have an old used nismo lsd too. You can buy the rebuilt kits from any trustworthy vendor that carry nismo products.
