1973 Duster dash wiring harness

Got a 73 duster, the dash wiring harnesss is completely destroyed, no fuse box, majority of wires are cut into, nothing works. What is a good harness to get which will be a somewhat decent harness to install for a beginner?
If you don't have one, wander over to MyMopar.com and download a 73 manual, which got there because of some of the guys right here.
