There is great bendix info on pages 570 to 572 of the Service Bulletins. As far as I know you cannot use a starter with a 5/8 shaft in place of the 1/2 inch shaft type without modifying the flywheel. Perhaps someone has a bendix available for a 1/2 starter. Post of photo or your damaged bendix someone may have a stash of old parts. good luck Supergnat
