Another Fender Tag question

so when I run the codes on my 74 Dart, 2 things stand out to me. The LL29 code comes back as it being a Demon, yet there is no (remaining anyway) signs or markings of it being a “Demon”. Secondly, an A88 code that come back as a “Dart GT package”.

So my question(s). I thought the “Demon” was a package, and even sought after, given the controversy surrounding the demise of the name. Was it nothing more than a name that was used prior to being called a sport?

What “makes” it a Dart GT pkg over the non-Dart GT pkg?
