Dash, no. Airbox, no. I believe you can get carbon fiber dash panel inserts. Wood grain too. I don't remember where.
For the most part, Bonneville owners tend to be anti-rice, and lean towards the domestic muscle end of the spectrum. You'll never see a fart can muffler on one of our cars, or an APC sticker. Carbon fiber is a ricer thing, so if there were any parts available, I doubt anyone here would even know about it.
