14 bolt limited slip question

[Russell]

Hey guys! My 4.10 14 bolt FF rear from my 79 4x4 rolling chassis has a limited slip in it, what will it likely be? A posi or a gov-lock?

When I open it, what am I looking for to determine what it is? Pics would be nice

If it is a gov-lock, I wanna know so I can be careful not to break it!

Gov-lok probably. They're stronger than the 10 bolt version, but you still need to be careful with it.
