another detail.....the pitman-arm was untreated, bare steal, so very prone to rust. I ordered RPM, from a company called ECS Automotive; bare steel part needs to be heated a little, smeared in with colorless RPM and this stuff will prevent the part from rusting, but you still keep the original bare look. Pitman-arm is untreated, bare; the snapring and nut were cleaned and i found out that the snap-ring is black fosfated, and the nut is natural cadmium plated.
