Hey Bruce...here's what I get

LR = axle code
W = assembly plant, Warren Motive, Michigan
33 = julian date code (33rd day of year)
E = Positraction source or Eaton
2 = shift

the LR code is a 3.36:01 axle ratio used from 1973-76. 1975 codes also called out included AW (3.08) and the AY (2.73) codes.
