1974 Dart Special Edition paint/vinyl top codes not found

It's an educated guess, but I'm pretty sure H5LL is a parchment bucket seat interior. I think the vinyl top code may be a typographical error since I can't find reference to a "P" color between '71-'80. "P" and "L" ain't so far apart on a keyboard, and L is Parchment--the same color as the interior--so that would make sense.
