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.
yep provided the 76 has the same brake type as the Dart. Drum brake spindle upper control arms are different than disc brake control arms. they can't be interchanged.

the lower control arms are the same regardless of brake type and CAN be interchanged.

leaf springs will interchange either way.
