2002 Z28 A4 -open or posi?

How do I determine if I have an open or posi rear? I would like to know and not rely on how my black marks appear when I mash the throttle.

Thanks and I really appreciate your help!!

All LS1s have limited slip/posi rears. Your 2002 should have a Zexel Torsen in it. It uses spider gears instead of clutches.
