First off all, sorry if my English is little rough, I`m from Croatia

I have a Sierra 2.0 DOHC 8V 122hp and an non LSD diff.
As I`m learning how to drift, burn, etc. I would like to fit a LSD diff.

Now, the problem is, that I don`t know what to look for.
I know how to figure it out iff I jack up the car, but, what if the diff is allready taken off the car?

How can i tell if it is an LSD one?

How does it look (If it looks diferently), are there some part numbers or some markings that can help me...

Pictures would help me a great deal.

Thnx
