Best Upper a arms for 72 a body

Hey everyone, i am curently swapping my front suspension to the dr diff kit, and as like always i noticed my front suspension was shot for a 40 plus year old car. Weird right.. Anyways, where can i find stock replacement upper a arms. Whats the best priced price a arms? I dont care if they're stamped steel or tubular. As long as they're decent priced and whatever works.
