Front End Swaps

Hey guys, im new in this A Body world, i would love to have a 70-72 Duster or a 72 Demon, here in Mexico the more common car is the Valiant Duster (a mix of the Dart Sport and Duster)
I was wondering if there is a way (i really hope there is) to swap the bumper, fenders and hood of a 70s Dart Swinger and put it on a Duster
Do i have to swap anything else?

I also have another question, is there a way to fit the 1969 Barracuda Gauge Cluster on a 70-76 Duster/Dart?

I really hope to get some help from you guys!
