Thundercraft LS v LD designation?

[Sunsetrider]

This is one of those basic questions where everyone but you knows the answer and assumes that everyone else does. I asked in the Thundercraft section but did not get a reply: what do the designations LS and SD denote, respectively? Both appear to have identical specs but I am trying to discover which of these applies to my target T-craft 1750 from 1990.

Actually it's LS and SD . . . same year, same size, same specs. Surely someone out there has the secret knowledge??

Time to settle this burning question: my review of ads would lead me to believe that the 1750 LS has 2 rear seats, one on each side of the doghouse, and a swim platform one one side of the engine only. The SD has the full width rear bench seat and swim platform.
