Yes, until recently I assumed only cars with X coded trim tags had the crayon markings. Then someone on this site mentioned that his early car (close to my build date) had the markings, so I decided to check my car to see if I had them. Sure enough they are there. I had the car for 25 years before finding this out. I do have an X code, it's just not on the trim plate. My package shelf doesn't look so great, but I'm glad it has never been replaced. The markings might have been lost if the shelf had been replaced.
