I promised to give an update on trying to find replacement parts or reman. steering gear box for my 1960 F600. Well, it turned out to be worn out gears; none to be found anywhere. Finally found one reman. gear box which was $700 + $250 core charge + shipping which I didn't even ask what that would cost. Finally located gear box (gears like new) at a junk yard local but worked hard removing it. Payed $150 for it, got it going today; works great. THANKS again to everyone who tryed to help me with info.!!
