These were submitted from a few 1970 Chevelle owners for the 1970 Chevelle registry I oversee,be it Malibu,Super Sport,Elcamino,Convertible or Station Wagons.There is too much to correlate with the 1970 information vehicles alone,so the few 69's I receive are just for comparison with the 70's.
I tend to believe the "L" stood more as an indicator for a Big Block,vs. a Super Sport.
