Data Plate Decoding 69 GS

[Louie B]

I recently purchased a 69 GS HT. The data plate doesn't seem to give me a paint code (it was originally DK GRAY met),( white int) but there isn't a #83 on the dataplate. don't know if it originally had a vinyl top or was 2 tone. If I email what the data plate says to someone here, could you guys help me figure this out? thanks
