I am restoring the fog lights for my April 68 Dearborn GT. The Osbourne FAM calls out 55738-S36 for the attaching nut, and C5ZB-15251-A for the spacer. I know the finish for S-36, but has anyone seen that finish for the nuts? Most of the original stuff I see appears to point toward a phosphate and oil finish (S-2). Also was the spacer bare metal or "finished", if finished, what was the finish?
