Interesting seeing pictures of a red leather interior in a 68 coupe. One of my 68s has a red leather interior, but its a convertible, so I have no headliner, rear deck, or shoulder straps. And I have a speaker grille in the middle of the back seat, above the armrest. Your leather is in a little better shape than mine too. Convertible interiors tend to get rather sun beat. I have shirts that are faded on the tops of the shoulders. My 68 coupe has a dark green interior.
