If you are in a pinch and can't wait for factory direct prefinished wood parts, I have experemented with several woods and matched my paneling. It looks to be about the same as yours. Birch ply is great, hardwoods soak in the stain too deep to get a proper color match. A light cherry over a wood conditioner works well. Condition the wood, then apply the light cherry, but don't let it sit too long. After it dries, a coat of wax will give it the same sheen as the factory (almost). Its also much, much cheaper then a facory panel.
