Most likely the side trim on a 65 is aluminum. A magnet will not stick to aluminum or stainless. If it's a 2 door ht., the belt moldings would be stainless, as would be the moldings on the front
of the sail panel. Much easier, ( but very time consuming) to repair stainless trim. Emblems, tail light housings, etc., chrome pot metal. Moldings on top of the 1/4's that tie in the tail lights
are stainless.
