Pre-L - small chrome bumperettes and 2-pod dash.
L models - rubber bumpers up front and a single bumper across the entire rear, and most have single pod dashboards.
Depending on when in 1972 your car was manufactured, you may have some characteristics of both the pre-L and the L model - some pre-L cars have single pod dashes and some rubber bumper cars have 2-pod dashes.
