Yes, same material for the snow flaps...They would be an exact match.
Ahh yes, those darn dash panels... They are a molded part. I work in the plastic injection molding industry, and making a mold for low quantities would be cost prohibitive. I could probably use the molding machines at my work to make them. It's the cost of building a mold that's the killer. I have tossed around the idea of making the dash parts from aluminum, then having them powder coated in wrinkle black. But that wouldn't be cheap either and it seems most guys want an exact match.
