Posi Questions, How can i identify one?

Im looking at this parts car here in my neighborhood and its supposedly an 85 iroc-z that has had the engine and tranny taken from it. the interior is gutted also but it has a good body on it. My main question to yall is how can i decipher if it has a limited slip rear, or a posi or anything amongst that sort? I know there is numbers but this would be a main factor into buying the car.

Thanks guys.
