Any code that has (91) in the description means that in 1991 that's the definition. Other years the definition may be different.

D42 is the roll up cargo shade. Even if it's gone the mounts in the hatch area should still be there.

The other code definitions aren't necessarily accurate either. A code can mean different things from year to year and model to model, if it sounds blatantly wrong, it probably is. Google is a good place to search for codes, just keep in mind if yu're not on a Camaro/Firebird website the definition has a higher chance of being wrong.

 

ok,that makes sence
