paint the adjuster pieces and see what happens. I bet it will be fine. Later down the road when you get some extra $ go ahead and get a black headliner and get the visors recovered with the same black fabric as the headliner.
That is exactly my plan at least. i plan on having all black up top, the stock grey in the middle and eventually a rear seat delete (I have a pitch black hatch) with black and grey Corbeau seats and black carpet throughout.
