Other than original build files or copies from the Kingston Museum, you might try Computer Keels for the proper NACA chord shapes for various vertical depths of your rudder. If the fore-aft distance is not much different from top to bottom of your rudder, a single template at ~ $75 is all you should need. They supplied templates for my centerboard trunk which my yard used to do the fairing over 2 separate haul-outs. Did the forward half of the trunk 1st and the next year did the aft section. Lots of lead removed/fiberglass added but Water Phantom is faster and now reaches the same speed on either tack--a good thing compared to before the fairing. YMMV since the rudder is a relatively minor (compared to the keel) perturbation to the underwater lift/flow.
