Assuming it's a limited slip don't forget to add the Ford additive to it, other wise it will pop..snap..and make all sorts of noise.
Is there any way I can tell if it is limited slip?
If it's a locking rear (posi) both wheels will rotate when you turn one. This is best done by just jacking up the rear for a minute and turning one wheel.
I'm pretty sure the gt and cobra trims all came with posis stock. The v6 did not.

It will have a trac-loc limited slip unless someone has swapped it out, which would be pretty lucky bc it's expensive to upgrade. So yes, you need the tiny bottle of additive depending on which oil you use. I have used Royal Purple in mine, it says on the bottle it already contains the additive, so I did not have to use it.
BtW Amsoil is fantastic!
It sure is okay. And recommended.
