Probably way cheaper and less trouble than dyeing/painting an old pair.
NOS also has the matching aqua door panel, bottom carpet only, if you want, and the matching floor carpet.
I went this route ... too easy.

...Dale says they don't stock the kick panels...kick panel carpet carpet yes but not the plastic kicks themselves. I imagine any used ones you could find would be in b/c...may have to improvise..
Nos good for you
