A notion has been proposed over at Team Chevelle:
"L" code = SS?
Baltimore built '69 Chevelles with an "L" on the bottom line of the trim tag are showing a trend of indicating an SS car. Still a long way from proven, but interesting nonetheless. They are looking for both documented SS and non SS Chevelles (Malibus and 300s). Dale MacIntosh has a decent collection of trim tags at
"Chevelle Stuff" .? Kansas built '69 Chevelles may have a similar trend, but Baltimore is being looked into for now. Thoughts?
