1971 and 1972 Dodge Demons.....did all the VIN's
The first L is for Dart the next is for low price class. But the real way to tell a Dar from a Demon buy the vin is from the third and forth digets.
23 is a 2-dr hardtop (Dart)
29 is a 2-dr sports hard top (Demon)
A Duster and Dart Sport are allso 29 as they are all the same body style.
and a Scamp would be a 23 as it is the same body style as the Dart.
