Hi Darryl, thanks for the information. My local ford dealer could not get me the parts but I called " All States Ag parts" as you suggested and was able to find a used differential in MO. Should have it here midweek and I can get the old girl back together and finish loaming my back yard and put in a sprinkler system. I turned 61 this year and having a small tractor for me is a must. I have been looking at the new compact tractors (Kabota B25D) but 20k after insurance and taxes is a tough pill to take so I will have to keep wrenching on the 1200.
Thanks again, Ken
