Door Decal/Tag Question
 

On the door decal the very last line that says MODEL: and then has a sequence of numbers and letters, does anyone here know how to decode those numbers. I would like to know what the sequence means on the two that I have pictured here.
Thank you, James

I’m not sure about the first two digit prefix, but the rest is the factory order code for the trim level. 1AL37 is a ZL1 coupe. Mine is a 1AK37.

Trim level order codes:

1LT Coupe (1AG37)
2LT Coupe (1AH37 )
3LT Coupe (1AH37)
LT1 Coupe (1AJ37 )
1SS Coupe (1AJ37)
2SS Coupe (1AK37)
ZL1 Coupe (1AL37)
1LT Convertible (1AG67)
2LT Convertible (1AH67 )
3LT Convertible (1AH67)
LT1 Convertible (1AJ67 )
1SS Convertible (1AJ67)
2SS Convertible (1AK67)
ZL1 Convertible (1AL67)

Thank you
