I believe that you are looking for the platform (4th digit) and the platform series (5th digit).. If you are referring to an Impala SS it's a bit sketchy because my lists show three different series numbers for the Impala but only one designation as a LS..
Impalas and Monte Carlos are both W platform.. ( 4th & 5th) WB - Impala and Buick Regal LS; WF - Impala and Regal GS; WH - Impala LS; WW - Monte Carlo LS; WX - Monte Carlo SS
I know that isn't exactly what you asked for but maybe it is enough to get you headed in the right direction for finding your answer.
