What is considered correct? Lynch road, nov 28 build, most parts on it are oct-nov date. What it had was tri castles on the uppers that are silver with a trace of black, no rust pits at all after evaporust soak, looked untouched but who knows. The right lower was a tricastle, silver trace of black, looked untouched, by cotter pin and dirt buildup, and is a factory ball joint, right side had a 6 castle nut, ball joint is a replacement, black nut. Is all tri castle correct, or upper tri castle, lowers 6 castle, and should they be the black phosphate. I know my 69 car had tris and 6s, but wondered if it had all tri castle on day one, is that possible? Thanks

it had all tri castle on day one

Thanks, thats what I sent to the plating shop, even filed 2 spares down so the cotter pins fit with new ball joints..in case I never find a good or nos left lower ball joint.
