There is an extremely scarce 139 tooth flywheel that was used on spray-oiler 235 engines, that used an 11 inch clutch. It uses a pressure plate with nine attaching bolts. Finding one to rebuild will be approximately like locating a chicken with lips. Unless you're planning on hauling a huge overload on a big rig, it's not worth the effort to get an extra half inch of diameter over the standard clutch and pressure plate.
