Yes. The LS, Luxury Sport (maybe Lounge Sport) has bolsters and the SS SunSport in 87 has captain seat and sun lounger.
The SS has a single hatch and the LS has two hatches. More seating room in the cabin of the LS.
if i remember correctly, the ls was bench rear seat and two buckets, some models had different decks also. the ss was a single bucket for the driver and a back to back passenger with a modified motor box.
