manual steering box

I rebuilt my box and used a Mancini fast ratio gearset, and the seals from FirmFeel. As per FirmFeel's directions, pack it with bearing grease, and top it off with 80-90w gear oil to fill the viods and keep all inner surfaces covered. The box didnt take much 80-90 as it was full of grease. I have been using this box for about three years, it is just as smooth as the day I built it.
