1968 gts seatbelts

The belts still have the tag on the belts labeled for the 4th quarter of '67 at least on the fronts. The rubber or plastic covers that cover the mounting hardware are missing so we were not sure. I will post pics of the missing items locations later tonight or tomorrow. Would anyone have a survivor or all original gts that could take pictures of their belts in relation to the color of their interior. I look on google at interiors and some are black while others are color matched so I am not sure if some were changed or if they are original belts.
Thank you
Joe
