paint code

Hi does anyone know where the paint code location supposed to be on a 1997 deville.

Have been searching with no luck.In the owners manual it says in the trunk on the outer wall on the pasenger side.Does this sound right?

I think it might be missing.

Is there somewhere online to put the vin # in to get the color codes.

I am looking to find the "interior color" code of the seats.

Thanks

Michael
