Contact Rod Geraghty @ 715-926-6096. Rod might be able to help you. Rod modified a OS pto to fit my CMB .21 R/S power head, which is mounted to a OS leg. The whole set-up looks factory stock. Very nice work. Richard DMost people have done there own mods. I did one for my Mac. I don't know of anyone offering a modded OS pto for any engine.Mike
