76 valiant suspension fit 73 dart?

i have a 76 valiant 4 door s/6 in the weeds. Was wondering if the control arms and leaf springs would fit on my 73 V8 k member and 72 Dart? My left side Uca is missing material around bushing from rust and the Lca has a crack by the hex. Also the leaf spring is broke where it holds the front bushing.
