Hi my first post. I built a farm tractor out of a 59 chevy truck. It was rolled. I removed the cab shortened the frame replace the front axle to a 3/4 ton. It has a 250 engine a combine HYD pump and 3point hitch.That was about 12years ago. I need the bearings that go on the input shaft top and bottom of the worm.I dont know what it was but i think it was a 1 1/2 ton it had 6 lug wheels.I have looked high and low. I think tomorrow i will go to a junk yard and get one of off a 57 but it has sat out one summer and i dont know what it will be like. Doug
