I just want to mention when I got my half doors off craig's, the person selling them called the interior black or charcoal. Can't remember, but when I got there to buy them they were dark slate which was a perfect match to my interior. The reason why I mention it is because sellers might not know what they have. My interior is dark slate and I was lucky enough to have the window sticker. That is helpful.
Hope you get a set. I love my half doors and my full doors are just sitting here. Might sell them if I can find a buyer locally.
