Mistral Pandera

Question
I'm a beginner (sailed once) and I'm cheap. I just bought a Mistral "Panera" from ebay. The board is in good shape, the sail has mold on it and boom seems to be a boom, all for $ 50. I then bought two carbon fiber masts from a friend for $ 50. He told that Mistrals don't have a universal mast to sail adapter and that I have to find the one for the "Pandera" model.
So, my two questions are; Do I have to find the "Pandera" model adapter or will another boards adapter fit. Hopefully a later model?
And, how do I remove mold from a sail?

Answer
Boards that old are extremely difficult to find parts for.  Mistral parts are not universal for that board.  No one keeps stock on old windsurfer parts. Mistral stopped making boards with mast feet like that long ago. The only online place I know that has some parts is the-house.com.   Look up their website and call them to see if they still have that part.  I think the correct name for that board is Pantera.  If you did get some good carbon masts in that deal those alone are easily worth $50.
