Changing Interior Color

Found a Fox vert that has the sterring wheel and top of dash in black but the bottom half and console in red. I hate the red. How hard is it to swap that out for black? Having a hard time finding all the parts. Also, when did the Fox's start coming with rear seat shoulder harness seat belts as opposed to lap belts?

Ok, so 92 started rear shoulder harness. interior color change doesnt look too hard. But the car I was looking at just wasnt worth the effort. My seacrh continues for a 92-93 red white or black gt vert. This is taking MUCH longer then anticipated. The condition of these cars is just terrible.
