GM used letters preceded by numbers for their RPO'* (regular production options), e.g. L was for motors, M for transmissions, F for suspension. I have the codes imbedded in my memeory on my old 71 chevelle which has L48 (270hp turbofire), M20 (wide-ratio 4 spd) F41 (heavy duty suspension) and Z-15 (SS). I really don't give much thought to the grocery getter car RPO'* but you will find them on your build sheet or under the spare tire cover.
