LSD or not?

I was about to make my move in buying a JDM LSD off this guy but since I just got the car, I wanted to see if already had it. So I jacked up the rear of the car, called my bro to watch both wheels, and drove it in first gear with the E brake off. My bro told me both tires spun at the same time. Does this mean I have LSD?

if you look, it will clearly say VLSD on the diffrential housing.. what year/model car do you have?

I have a 92 LE Fastback. I spun one wheel manually and the otherside didn't seem to spin at all so my friend said I don't have it.
