I could be wrong but I would say it looks like an open diff set up to me.

Does not look like any locker I have ever seen. And a LSD with no springs of any sort? Once again maybe I could be wrong.

I would just call my local rear end shop and they should be able to decipher the numbers for you.

You are mistaken. It is a factory trac-loc limited slip. It is not a locker. They don't use springs. There are friction discs behind the side gears.

It's a trac loc and unless the clutches are brand new or less than 5k on them it'll work just like an open diff. I'm sure some people on here like them but of all the LSDs I've ran they are the worst and wear out the fastest.

Mine old D35 with trac loc had 130K on it and worked great. If it wasn't a D35 I would have just ran it like that.
