I just did some digging Gary, that gearbox is for a B9200 with a serial number under 52071. The drawings look identical and they do use the same bearings gaskets and o-rings but the rest of the parts are dif numbers. Can you get some measurements off of it? If its close and will bolt in I would still be very interested, who knows maybe its just a little longer or something. If you can get me the measurements center to center on the mounting bolts, front to back and side to side, and length of the column, that would help.
