Default How can I tell if my ti has an LSD or open diff?

I have a 96' ti. Probably the base package. How can I tell if it has an LSD or what type of diff? Actually, I don't even know what the difference is. I've been reading a lot about it but its a difficult concept for me to take in.

Thanks in advance.

Edit: Also the last 7 of my VIN are AS95300 if it makes a difference.

Sorry again for the probably stupid question.

you could jack both back wheels up and spin them, if they spin in the same direction you've got LSD, if they spin opposite you don't

Also on the diff case there is a serial number. I believe if there is "S" in it, it's an LSD. There's also a metal tag on of the bolts that I think designates this as well. If you have a base model it's most likely an open diff.

3.45 if you have a manual transmission, 4.44 if you have an automatic

true, I kinda forgot about that, mainly because every car in New England is so rusty you can't even see that stuff
