1969 Cougar XR7 Front suspension rebuild

*Rebuilding the front suspension and brakes on my cat media blasting brake sheilds sway bar and was wondering about painting some of the parts in black. I want to restore it to original out of the factory. What do i paint and what color?

Upper control arms are bare steel. Spindles and calipers are bare steel. The brake rotor sheilds were dipped in semi gloss black paint. The lower control arms are dipped in semi gloss black on the inboard side. The outboard half and the outboard ball joint is bare steel. The steering tie rods are a hardened steel, bare metal.
