Dont drill a $$$ D-64 '65 2X4! Sell it and buy a $$ Edel D-66 or Offy 5615 (both later model duals) Offy still makes them $516 for either early or late bolt pattern, can even get a high rise, offy 5698 for about $598 As for making it fit, just chuck up a drill and lean it into the boss. then face the bolt top to match the angle. did that to a Performer onto a 65 A. worked great. Cheap AL casting is pretty soft.
