I recently bought a John Deere 3 pt, 2 bottom (16) 810 plow to restore. Need new points for it. I've only taken one of the points off so far and can only make out the number 350 on it. There are other letters, but not sure what they are. Hopefully the other one will be easier to read when I get it off. Does anyone know what the part number is, if other points will fit, and/or where to get them? Thanks
