Thanks for all of the reply's, I have been away from the computer for a few days.
The new photo of the pitman arm is numbered 78-3590 after the symbol 2-1?
JM 35 Sedan and V8COOPMAN , thanks for the photo's and explanation. Could the column have been assembled with different parts from other years or factory with different year parts. The forum continually increases my knowledge of these old Fords.
Will be putting this in the for sale section, not sure of the value. Maybe someone can put it back on the road with a fair price on the column.
Thanks everyone
Bob
