Jack up the rear and see if the rear wheels spin the same direction. If they do, you have an LSD...

Or post your VIN or see if you can find the VIN decoder. I "think" the VIN will ID the LSD...

Or look for the LSD sticker on the diff...

Axle code is G282/G284 for non-LSD equipped vehicles, G285 for LSD-equipped vehicles. This is on the sticker in your driver's door jam, it will say A/TR, this is your Axle/Transmission code.

Sport package USA 89+ N/A models had PPS, TEMS and LSD. LSD was also an independent option that could be had separately.
Sport package Canada 89-90 N/A models had PPS and TEMS as options, LSD was standard.

Who knows, could have been a Canadian car ;).
