The front will be an open diff; the rear could be either. The LSD diffs had a sticker on them from the factory, but whether it's still there after all these years is another issue. You could look up the axle info using the factory service manual. Or, you could jack up the back of the vehicle and put it in neutral. Turn one of the rear wheels forward. If the opposite wheel on the axle also turns forward, then it's an LSD diff. If the opposite wheel turns in the opposite direction, it's an open diff.
