Aftermarket LSD?

Aftermarket LSD?
Hi guys. I'm new here, just got my 2004 Fairlady last week. (I'm from new Zealand and we get Japanese models here).
From the advice on the forum it looks like I have the base spec model, but after driving it I suspected I might have got lucky with an aftermarket LSD.
I jacked it up, put it in neutral and rolled a wheel. The wheel on the other side turned in the same direction.Then I put it in gear and did the same thing. The wheel was much more difficult to turn and this time the wheel on the other side turned slowly in the opposite direction.
Sounds like this might be good news, but does anyone know if this confirms an LSD?

honestly, i would say the quickest way to figure that out, I say do a burnout wherever, then go back and look at tire tracks, if theres 2 long black lines if there is only one black line, well then your outta luck and gotta buy yourself one

Open diff if it spun in the opposite direction at all. Placing it in gear should make no difference other than making it harder to turn.

Yeah I wasn't sure since I don't know too much about it but I read this on another forum which kind of made sense:
"If you want to be more certain about having a VLSD or not, raise the rear end and put the car in gear (engine off of course). Then spin a tire. If it's open, it will feel fairly easy to turn. With a VLSD, there will be a good amount of resistance. Locking the driveshaft by engaging a gear will force any movement to go through the VLSD itself. Leaving it in neutral will not and will feel the same. There is also potential that if something for some reason binds slightly in the spider gears, the opposite wheel may turn in the other direction"
