Charlie. There are some very good repros usually for sale on ebay. Remember, though, that yours was custom installed at the factory. Any replacement will require, usually, that the screw holes be filled (with a dowel) and new holes drilled. Also the exact shape of the butt end of the stock was finished by hand, so you will probably have to file/sand the replacement part to exactly match the stock. It'll look great when done. however. Good luck..
