In 1968, how was the carpet color determined in a Road Runner? I have seen numbers for the interior color, but nothing on what carpet color went with what. My 1968 Road Runner was ordered as a red exterior coupe with red interior. It has red headliner, dash, doors, and seats but the carpet is black. It even still has the original long floor mats, which also are red. When I saw red was an option for the carpet, I was surprised to see it as black in this car. This is the original carpet and interior. I just wondered if there was a standard, ( in 68 there were very few consistent rules) or was this an open option left up to the customer?
