M_Boats: M-8 Rudder and Centerboard

My brother was lucky enough to purchase the Montgomery 8 recently posted on the Seattle Craigslist page. He says the boat looks great, especially for the price, came with a full sail rig, but is missing the centerboard and rudder. Does anyone have any information on what the rudder and centerboard should be for the boat so new ones can be fabricated? Or, even better, does anyone happen to have a rudder and centerboard for an M-8 laying around? David GrahBishop CaliforniaMontgomery 15 - Sky
