The front end reveals a seldom seen detail—spot welds in the unpainted, bare metal of the front unit-body framerails. Almost every older Mustang has surface rust on bare metal under the car. Minor restoration to remove the rust smoothes these original spot welds. The front suspension finish is bare metal for the tie rod ends, drag link, Pitman arm, idler arm, rotors, strut rods, sway bar hardware, and ball joint ends of the control arm. A well-known factory procedure is the inner halves of the lower control arms are dipped (not sprayed) in black paint. Spindles are bare metal, but heat-treated steel, which gives them a darker gray look.
