dude, r u serious?
jack up the rear of your car (leave in neutral,handbrake down). use ur hand to spin one tire and check the other tire. if they go the same direction u have LSD if opposite direction u have open differential.

or....just do a burnout and check the tire marks on the ground. two marks u got LSD, one mark u don't.
