The Sport S as Fudge says has the uprated suspension and the newer curvy dash along with the X20SE 20l engine, there where new wider axles and things like 16" wheels and nudge bars added too.
Probably just the suspension TBH, as I'm fairly sure my 2.8TDi SWB is a Sport S, and that's got the square dash too. I know there was a huge array of special editions too like Niagara, Apache etc.
Yer as it would have been on the cross over date usually 95, as all the 2.8's SWB and LWB have old square dashes but uprated (coil) suspension and wider axles. I think its to use up parts left over
