RARE 340 wedge car???

on my fender tag the interior says L6XV ive been looking around a couple days the only interior code 4 hemi orange i could find was H6XV anyone know about that and wut is the deal with the tag with "10" on it that is with the fender tag thanks

L6XV is the Low grade/trim interior
H6XV is the high grade/trim interior

Both in black/orange

The H and L designate the trim level.

The other tag is an inspection tag as the car travelled down the assembly line.
