Which part? I've seen CF hoods, T-tops, and Trunks. You might wanna try
http://www.teamdelsol.com. They should have links to it to places that might have what you're looking for. I think the CF roof goes for around $4-500... not sure... there's also a tinted glass(?) roof made by ameripol. Both use the factory parts off your top to hook up to your sol. If i see something, i'll let you know.
