Look at the diff, and see if it has a "Use LSD Oil" sticker/tag on it...if it does, you have a factory LSD (Was an option, std on SE I think).

That changes what options you have.

The factory LSD is pretty bad compared to the tighter aftermarket options....and limits what you can replace in the carrier, etc.
