I need an original pitman arm for my 67 GT 350. The outside of the shaft measures 1" I'm putting it back to the original power steering. Anyone have one? Randy
rcgt350 You need a plain old Mustang pitman arm. Since you mentioned your Shelby has a 1" shaft, you will need a C5ZZ 3590 A which is correct for a car built before May 1st 1967. Cars built after that date use part number C7ZZ 3590C. The C5ZZ part should not be too hard to find NOS. Goodluck! shlby66
